Virtual.Lab Motion is the next generation of the popular DADS product. The DADS/Plant connection to MATLAB and Simulink is a widely used and powerful solution for connecting multibody dynamic equations of motion with control and hydraulic models to produce more complete and accurate coupled dynamic systems. Virtual.Lab Motion user's a new solid model interface to make modeling more powerful and easier. The product is used to solve the constrained nonlinear equations of motion (coupled differential-algebraic systems) and report the positions, velocities, accelerations, and reaction forces of all parts in the system.

Typical end users of Virtual.Lab Motion with Simulink are engineers simulating mechanical systems for load prediction in new designs, performance assessment and optimzation, and trouble-shooting. Users are often involved in automotive, construction, military, and aerospace engineering. Other users are in the robotic, equipment manufacturing, amusement ride development, and other industries.

Users who have existing Simulink models of control systems can link them with Virtual.Lab Motion using the S-Function feature. All outputs from Virtual.Lab Motion (position, velocity, and acceleration of parts), and all inputs to Virtual.Lab Motion (forces or torques acting on parts) are passed through a single S-Function element. The process of connecting Simulink with Virtual.Lab Motion is fully automated and users have a minimum amount of work to do in using the combined solution process. Once the Simulink model is connected with Virtual.Lab Motion, the MATLAB solver performs the integration of the combined equations of motion and control state equations to produce time-domain results for position, velocity, acceleration, and reaction forces from the mechanical system, and control states from Simulink. Results can be plotted as normal in MATLAB, and mechanical system results in Virtual.Lab Motion. The complete model can be animated in Virtual.Lab Motion.
