Robust optimal design of multi-body systems

Techniques in robust optimal design of multi-body systems are presented. In order to define the concept of robust optimal design, a performance variance minimization method is applied on variations of design variables. The regression model is estimated through a response surface methodology to evaluate the performance variance of multi-body systems. The experiments necessary for the response surface methodology are not conducted through physical tests but through nonlinear multi-body dynamic simulation. The techniques presented are applied to a rotary-type compressor in order to apply them to the robust optimal design of a weight balancer for use in vibration control and to show the effectiveness of the techniques.
