Method of Durability Analysis for Danamic Load

摘要

According to the present invention, a durability analysis method using a dynamic load comprises: a system model construction step of constructing an entire multi-body system in a multi-body dynamics model based on a rigid body; a rigidity analysis target designating step of designating a rigidity analysis target body requiring rigidity analysis among bodies of the multi-body system; a rigidity analysis step of analyzing rigidity of the rigidity analysis target body; a rigidity compensation modeling step of replacing the rigidity analysis target body of the multi-body dynamics model with a rigidity compensation model incorporating the rigidity analysis in the rigidity analysis step; a load calculation step of calculating a load result in time of a connection component portion of the multi-body dynamics model to which the rigidity compensation model is applied; a durability analysis target designating step of designating a durability analysis target body in the multi-body dynamics model; and a durability analysis step of performing durability analysis of the durability analysis target body based on the load result. Durability analysis incorporating a dynamic load applied to a body can be performed by a single integrated process.
