Powertrain Mount Loads Prediction and Sensitivity Analyses

A method to predict the powertrain mount loads is proposed and correlated with measured data. DOE studies are performed to derive the sensitivity of several variables, including the range, root mean square, pseudo-damage values of powertrain mount loads, on some model parameters, including powertrain CG locations, moments of inertia, and mount stiffnesses, respectively. The results show that the proposed method is valid in predicting powertrain mount loads.
