Abstract
Automotive powertrain mounting systems were one of the main vibration isolation systems of vehicles,which had great influences on its performances for the vehicle noise,vibration and harshness(NVH) experiences.Considering the powertrain mounting stiffness existed a certain degree of errors or volatilities,Chebyshev interval method was applied to calculate the natural frequencies and decoupling rates of powertrain mounting systems varied with the extents of element stiffness change intervals,and the calculation accuracy was determined based on examples.To improve frequencies of the mounting systems and robustness of decoupling rates,robustness optimizations were conducted according to the interval optimization models of frequencies and decoupling rates of automotive mounting systems.Results show that the optimization method may obtain better energy decoupling rates,high robustness and reduce the vibration transmissibility from mounting systems.关键词
