| Abstract: | In order to improve isolating performance of the power-train mount system of some vehicle,an optimal design is made for mount's stiffness by multitarget optimization method,in which uncoupling of the energy is the objective function.With the signal to noise ratio as statistics,the robust analysis for the optimal result is done with Monte Carlo method.To compare with the original system,the result through the calculating testing shows that uncoupling of the power-train mount system with the optimal design ha... |
