Notes de l'éditeur
- LMS is uniquely positioned as solution provider, having both: - A strong HW/SW Tools portfolio (Test and Simulation) - The related services LMS perceives this position as a strategic advantage as most (all?) of its competitors: - Only sell tools without a strong service engineering support capabilities OR - Only provide services without any interest to make customers self-reliant using industrial tools LMS this “solution approach” is specific relevant for MI companies, as it provides an overall toolkit to get the issues solved LMS invests a lot in R&D in order to remain in the forefront of relevant technology innovation - Through organic growth OR - Through well selected acquisitions LMS has a healthy financial track record , allowing the company to continue to invest in R&D/innovation
- We are proud to be part of a global company, having - 33 sales offices/representative throughout the world - 15 R&D/services centers This global presence allows us to support customer world-wide - Be there to support them in their local language - Furthermore it presents opportunities for further ideas/product roadmaps, making us even more relevant to customers…
- This slide represent the complete portfolio of LMS. - Test.Lab is the platform for mobile and lab testing of physical prototypes - Virtual.Lab is the 3D CAE simulation platform (closely linked to CAD) - Imagine.Lab is the platform for multi-physics modeling (authoring) as well as system synthesis (supported by a system data management system) - As required Test and 3D data can be integrated to represent an overall system/subsystem as part of a “functional mockup” In addition LMS has a strong engineering and deployment capability, helping customer tackling a wide range of engineering challenges as well as supporting the deployment and integration of the LMS tools
- ES is enabler of LMS engagement model. Our solution includes: People: We are a people business and we realize we charge a lot for them, but they are our core value: they bring our knowledge, experience and flexibility. Know-how: We bring experience – related to people – in terms of application know-how, project management/process as tool usage. We also provide process audits –what is the current engineering process (e.g. acoustic target setting), what are the bottlenecks, how can we improve this Tools: Having the proper tools in place, ranging from test hardware, CAE software and test facilities, takes away the customer’s burden of selecting tools and trying to understand how they work. -> focus on process efficiency, optimal performance, best in class technology set up Process: The value of having a process in place cannot be understated we have worked in the industry for so long that we can manage this for him and implement it. On top of that , we are ready to provide real technology transfer -> focus on process efficiency, optimal performance, best in class technology set up LMS considers its engineering services key to help customer solve development challenges. However, the LMS mission is not only to solve the today’s customer issues, but also to make the customer more self-reliant by securing appropriate know how transfer of tools and process…
- LMS provides engineering solutions throughout the development phase… This development phase is represented by a “development V for mechanical engineering” and eventually a parallel “development V for SW-controls engineering) Since the 1980’s, LMS helped (and still helps) customers testing the physical prototype at the time of product or component HW availability. Although the need for such final “real-life” validation remains very critical, LMS has introduced in the late 90’s the unique concept of “hybrid” engineering, using physical testing to improve accuracy/usage of 3D CAE simulation. This allows customers to frontload more design decisions (in the absence of a physical prototype) as the accuracy of CAE simulation is further boosted. In the last years, LMS is heavily promoting design options to be simulated in the absence of a 3D geometry by using multi-physics system modeling techniques as from the architectural/concept phase of the product development. This modeling technique is the ideal approach to integrate HW and SW engineering activities if required. Thanks to the recent acquisition of Emmeskay, LMS is now in an unique position to help customers bridging both distinct development worlds…
- Starting with Virtual.Lab Structures – the unified modeling environment
- To create the system simulation model in LMS Imagine. Lab AMESim, users can exploit a large library of pre-defined and validated components from different physical domains, such as fluid, thermal, mechanical, electromechanical, powertrain and many others. These libraries eliminate the need for extensive code writing and enable development teams to easily create complex system models covering multiple domains. The accelerated modeling frees up valuable engineering time that can be used to optimize designs. The library components are all completely validated, which guarantees the accuracy and the reliability of simulation results.
- LMS Imagine.Lab AMESim is an open platform enabling an efficient integration with third-party software tools for control, real-time simulation, multi-body simulation, process integration and design optimization. LMS Imagine.Lab AMESim also provides a generic co-simulation interface to couple multi-domain system simulation with any kind of 3D dynamic models, for example for computational fluid dynamic simulations or finite element analysis. This allows LMS Imagine.Lab AMESim to be seamlessly integrated into the extended digital development process. --------------------------------------------------------------------------- CFD / means Computational Fluid Dynamics MBS / means Multi Body System EM / means Electromagnetism PIDO / means Process Integration and Design Optimization
- Please, insist on the both graphs which are showing than: . AMESim is a suite tools (no only one product) . AMESim technology could be deploy for several communities AMESim enables users to build complex multi-domain system models through the interactive graphical interface. The resulting sketch is easily understandable and offers a logic representation of the system model under investigation. AMESim is based on a validated collection of components issued from different physical domains. AMESim focuses on physics-based building blocks, frees users from all numerical model creation and code writing tasks, and gives direct access to the analysis and the optimization of the design. Based on the most advanced numerical integrators, the AMESim solver supports ordinary differential equation (ODE) and differential algebraic equations (DAE). The solver automatically and dynamically selects the best-adapted calculation method, depending on the dynamics of the system, among 17 algorithms. AMECustom is a customization tool that allows to adapt applications to the end-users’ requirements. With AMECustom, company-specific model databases can be built, with custom user interfaces and parameter sets. In addition, AMECustom offer the possibility to protect sensitive information through encryption facilities before supplying models to third parties. AMERun offers a run-only version of the AMESim software, dedicated for users who simply want to run a packaged simulation model to analyze and visualize different design alternatives. With AMERun, engineers can easily share their validated, tested and customized AMESim models with nonexpert users. AMERun offers most of the features available in the standard AMESim environment to set model parameters and perform analysis runs. AMESet, the submodel editing tool of AMESim, is designed to assist users in writing well-documented, standardized, reusable and easily maintainable libraries. By following simple rules, component models become fully compatible with the existing AMESim models and are automatically usable on each supported platform. AMESet is also perfectly adapted for the re-engineering of proprietary simulation code.
- LMS Imagine.Lab AMESim offers an extensive set of tools to optimize the design cycle . These tools include facilities to optimize your design, to perform the analysis of multi-domain systems, to analyze graphically simulation results or to generate customizable HTML reports. AMEAnimation is useful for visualizing the results of AMESim simulations as a 3D animation scene. Users can develop animated representations of an AMESim simulation by creating objects in AMEAnimation and linking them to the results of the simulation. Animated 3D scenes offer a higher level of demonstration and you can visualize the physical behavior of components according to the parameters you enter and the results of the simulation. Analysis tools such as Fast Fourier Transform, spectral map, linear analysis order tracking and activity index helps to understand the behavior of the system, highlighting the main dynamics and enabling the user to simplify the modeling with a handled lost of accuracy in the results if required. A lot of information about the intrinsic behavior of the system is available using Linear Analysis. AMESim includes a comprehensive set of methods: eigenvalues, modal shapes, root locus, transfer function representation thanks to Bode, Nichols and Nyquist plots.
- Our solution is based on the AMESim-Simulink interface since Simulink is de-factor the standard for the design of system control. The idea is to offer the possibility to develop the physical system model within AMESim and to set-up a model of the control in Simulink and to couple the two tools. 3 types of interface are provided in AMESim: The co-simulation means that each software use its own numerical solver. AMESim&Simulink exchange data during synchronisation meetings (in practice, AMESim can send sensor signals and get actuator commands from Simulink). This is used mainly during the function specification stage. It is also possible to export an AMESim model in Simulink in the form of a S-function. This is used for the implementation and validation stages. In this case, both models used the Simulink solver. The third interface is the import of a Simulink model in AMESim to generate a SIL environment directly within AMESim.
- These plots show that as soon as the load orifice opens, the downstream pressure is too low, the pressure acting on the membrane is weak and the pilot valve opens; pressure in the upper chamber is released and the main valve opens following the pilot (opening phase). On the other hand, when the downstream pressure raises, the pilot valve closes. Pressure in the upper chamber raises also and tend to force the membrane to close the main valve which follows the movement of the pilot (closing phase).
- The pilot closes far more faster than the main valve as shown in the following plot: These plots show the way the valve regulates the pressure. Indeed, the pilot valve is set at a given downstream pressure to be maintained. If the downstream pressure is higher than the setting pressure, the main valve works in closing phase until the setting pressure is reached. When the downstream pressure is below the setting pressure, the main valve works in opening phase until the setting pressure is reached downstream.
- The line submodels include resistance, inertia and compressibility and, hence, generates wave dynamics. These wave dynamics are often responsible for localised instability in the system. In this model, this instability takes place in the hydraulic chamber of the pilot valve and generates high variations of pressure during the opening phase. The nozzle influences the correct operation of the valve. Indeed, a right nozzle size is a good compromise between time needed to regulate the system and regulation stability

- This is an example of a company designing cold rolling mill systems for steel plate production line. On this type of system, there is a very well-known effect that appears, you accelerate the speed of the system if you want to increase the productivity, but you reach a point where the system becomes very unstable. This system is controlled by an hydraulic circuit and the customer used AMESim to find a way to increase the accuracy and precision of the hydraulic control system to increase the productivity and the speed of the plant. The increase of the accuracy of the system must be done but they needed to avoid that they have these oscillations appearing to keep the sickness of the plate constant. They used AMESim to model the full hydraulic system but also the control logics that control the pressure in the hydraulic system to avoid oscillations and unconstant thickness of the system.
