摘要：
This paper presents computer simulation methodology for dynamic stress time history computation to predict the fatigue life of machine components using flexible multi-body dynamics. A hybrid method which employes stress superposition as a function of constraint loads and component accelerations that are predicted by flexible body dynamic simulation is utilized and implemented using established codes. A system integration methodology for dynamic stress computation of mechanical system components is described to provide a usable environment for an engineer. It uses a database management system such as the IAC and the established dynamics and finite element analysis codes.
