Abstract
This vehicle body stiffness analysis method involves a computer performing stiffness analysis using an automobile vehicle body frame model 1 that includes fixing/connecting parts 3 for fixing or connecting fittings or lid components, and is formed using flat elements and/or three-dimensional elements, wherein the analysis method is characterized by comprising: a mass-assigned vehicle body frame model generating step S1 in which masses corresponding to the masses of fittings or lid components are assigned at prescribed positions within regions where the fittings or lid components are fixed or connected by the fixing/connecting parts 3 of the vehicle body frame model 1, thereby generating a mass-assigned vehicle body frame model 21; and a stiffness analysis step S3 in which stiffness analysis is performed on the mass-assigned vehicle body frame model 21, the analysis taking into account the inertial forces which act upon the automobile when travelling.
