S16-4 ADM740, Section 16, June 2007 Copyright  2007 MSC.Software Corporation Adams/Car Mechatronics (Cont.) ● You can use Adams/Car Mechatronics to easily incorporate control systems into your vehicle models. It contains modeling elements which transfer information to/from the control system. ● The benefit of using Adams/Car Mechatronics is that it shares data and simulation components with Adams/Car, as well as the control system development code you are using. This means that complete system-level optimization is made easier for complex problems such as shunt-and-shuffle, ABS impact on ride/judder and so on. ● You can load the Adams/Car assembly containing a control system as any other assembly, without having to perform several manual tasks to run the coupled simulation. ● Adams/Car Mechatronics includes a Signal Manager for setting up the connection between the transducers/actuators and the control systems.

5. S16-5 ADM740, Section 16, June 2007 Copyright  2007 MSC.Software Corporation Benefits of Adams/Car Mechatronics ● Using Adams/Car Mechatronics you can: ● Explore the performance of your coupled mechanical/controls design and refine your coupled design before building and testing a physical prototype. ● Analyze design changes much faster and at a lower cost than physical prototype testing would require. For example, you can change springs with a few mouse clicks instead of waiting for a mechanic to install new ones in your physical prototype before re-evaluating your design. ● Vary the kinds of analyses faster and more easily than if you had to modify instrumentation, test fixtures, and test procedures. ● Work in a more secure environment without the fear of losing data from instrument failure or losing testing time because of poor weather conditions. ● Run analyses and what-if scenarios without the dangers associated with physical testing.

6. S16-6 ADM740, Section 16, June 2007 Copyright  2007 MSC.Software Corporation Methods of linking Control System ● Adams/Car Mechatronics provides three different methods to link the control system to the vehicle model. ● Controls System based on Function Expressions. ● Compiled Control System Representation – Use Controls code generated by software such as Easy5 or Matlab/Simulink. ● Co-simulation – Adams/Solver solves the mechanical system equations and the control application (eg Easy5 or Matlab) solves the control system equations.
