The impact comfort is one of the most important attributes of the ride comfort, and the after-shake plays a key role in the impact condition, which affects the driving experience directly. To investigate the effect of system parameters on the after-shake, a simulation model adopting the latest modeling methods is established and DOE (Design of Experiments) is carried out according to the EMDO (Evolutionary Multi-objective Data Optimization) workflow. The results show that the powertrain mount can affect the after-shake remarkably, followed by the suspension and tires. The after-shake can be improved by increasing the mount stiffness and loss angle. However, there are many limitations to enlarge the stiffness of mounts. Such as the idle vibration worsen by increasing the mount stiffness. Given the performance conflicts, a multi-objective optimization method is described.
