Abstract:
There are several kinds of mechanical systems that are under event-triggered conditions. For the dynamic analysis of such mechanical systems, a simulation program that can generate equations of motion for mutibody systems in the discrete-event simulation framework was developed. For complex multibody systems, a dynamics kernel was developed to generate the equations of motion for multibody systems based on multibody dynamics. To generate the equations of motion, the recursive formulation method was used. Using the developed dynamics kernel, the dynamic responses of multibody systems can be carried out under continuous conditions. The general multibody dynamics kernel, however, cannot deal with discontinuous-state variables and event-triggered conditions. The multibody dynamics kernel, therefore, was integrated into the discrete-event simulation program to deal with multibody systems in discontinuous environments. The discrete-event simulation program was developed based on the discre
te-event system specification (DEVS) formalism, which is a modular and hierarchical formalism for analyzing systems under event-triggered conditions.
