- Abstract
- The performance variation of a multibody system is affected by a variation of various design variables of the system. Therefore, effects of design variable variations on the performance variation must be considered in design of a multibody system. Accordingly, a variation analysis of a multibody system needs to be conducted. For a variation analysis of a multibody system, population mean and variance which are called parameters of design variables are needed. However, an evaluation of population parameters of design variables is impossible. Therefore, an estimation of population parameters of the performance based on sample mean and variance which are called statistic of design variables is needed. In this paper, the analytical variation analysis method for multibody system based on design variable samples was proposed. And, using proposed method, a variation analysis of the vehicle ride comfort based on sample statistic of design variables was conducted.
