Two types of suspension with inerters were designed. The mathematical model of suspension with inerters was built. The suspension with inerters ofⅠandⅡtypes were set up. With the multi-objective optimization methods, the performance parameters of the two types were obtained. Based on the simulation, the bench test was done and the simulation was consistent with the test results. It shows that the suspension with inerters exerts the feature that spring was phase leg, damper was neutral and inerters was phase advance. The vehicle vibration isolation performance was increased and the comprehensive performance of vehicle was coordinated.
