摘要：

Taking the mount stiffness as design variables with the uncertainty of design variables and inertia parameters of powertrain described by both normally and uniformly distributed random variables respectively, a reliability optimization model for the natural characteristics of mounting system is established and both certainty optimization and reliability optimization are conducted respectively on the natural characteristics of a car powertrain mounting system. The results show that compared with certainty optimization, using reliability optimization though slightly lowers the decoupling rates in all directions of mounting system but can significantly enhance its reliability of decoupling layout and frequency allocation.
