The engineer’s modeling capability is the weakest link in the chain that supports the simulation of dynamic mechanical systems, due to the fact that engineers are forced to define mechanical system models in a way they are not familiar with. Advanced developments in computer techniques, computer graphics, and recursive computational algorithms for mechanical systems make the high speed dynamic simulation and graphic animation of mechanical systems feasible. But without a practical, useful modeling tool, the engineer has difficulty in using these advanced techniques.
The Dynamics Workstation is a modeling tool developed to help the engineer define mechanical system models in a natural, practical way. The engineer can communicate with the workstation naturally and interactively, define the model in formats that meet the needs for both high speed dynamic simulation and conventional dynamic analysis, define and assemble the model body by body using a relative coordinate system, visualize the configuration of the model, carry out simple joint exercises to detect the errors of the model in the early design stage, graphically lock and unlock joints, and adjust the system configuration even after initial assembly. The workstation automatically generates the mechanical system model based on the engineer’s interactive input data. The model design system strengthens the engineer’s modeling capability; it not only improves the design quality, but also boosts productivity.
