英文摘要：

In order to meet the energy recovery and performance optimization of hydraulically interconnected suspension,a hydraulically interconnected energy-regenerative suspension was proposed.Combined with the structural characteristics of the reverse interconnected suspension, the energyregenerative mechanism was introduced,and the dynamic model of a 4-DOF vehicle suspension was established. The vehicle dynamic performance and the energy-regenerative effect were simulated by using the joint simulation AMEsim / Simulink. The α-method was used to calculate the weight coefficient of evaluation indexes. The parameters of the spring stiffness and hydraulic cylinder diameter were extracted from eight potential parameters by means of design of experiment to perform optimization with genetic algorithm in Isight. Both vehicle dynamic performance and energy-regenerative effect were optimized.Based on simulative computation,the bench test of full vehicle was carried out under linear condition on a random road using the 4-poster road simulator. The results showed that the vehicle dynamic performance of the new suspension was slightly worse than that of the traditional interconnected suspension,but it can meet the most road conditions and recover part of vibration energy under the premise of maintaining ride comfort.
