MOTION ANALYSIS

Motion Analysis & Combined FE and Motion Analysis

Motion analysis provides engineering simulation from a different angle. When the motion of a system is complicated (flight simulator, driving simulator), motion analysis can provide information on velocity, acceleration, reaction force of the moving components.

Motion analysis can be used to check whether there is an over constraint in the design which may prevent the intended component movement.

The information of acceleration of a moving component can be important so that the assessment can be made to judge whether it is safe to have equipment to be linked to that component. If the moving part is a seat and these is a passenger sit on it, the motion analysis will be able to provide information on safety assessment or implication on health.

The components in motion analysis is assumed to be rigid bodies. The information from motion analysis can be fed into FE structural analysis as loads or boundary conditions so that further stress analysis can be carried out under these dynamic boundary conditions.
