A method for inherent characteristics analysis of powertrain mounting systems by considering parametric uncertainty and correlation

In order to deal with the complex situation that parametric uncertainty and correlation coexist in the automotive powertrain mounting system (PMS),an uncertainty analysis method for calculating the natural frequency and decoupling rate of PMS was proposed.In the proposed method,the multi-dimensional...
