In order to improve the isolating performance of the power-train mount system of one light truck with the uncontrollable parameters of the stiffness and location, a robust optimization design problem based on the 6-DOF dynamical equation of the power-train mount system is presented in the paper. For the robust optimization design of the power-train mount system with the uncontrollable parameter variations, a deterministic, non-gradient approach for objective robust and constraint robust optimization is discussed based on the design of orthogonal experiment and Genetic Algorithm.

The power-plant of the truck is one of main vibration and noise sources which often result in drives' uncomfortable, steering wheel and rear view mirror vibration and so on, because the diesel engine of the higher vibration and noise operation is used. The rubber mounting system had been used to isolating the power-plant vibration in truck. But, the conventional design optimization may not always satisfy the designed targets duo to the significant uncertainties in the rubber mounting system. In the paper, the method of robust design methods is used to minimize the quality effect of uncertainties on the power-plant isolating system. The 6-DOF dynamical model of the power-plant isolating of the truck is established for calculating the performance and robustness.
