车辆蓄能悬架系统仿真与试验

Simulation and Experiment of Vehicle Inerter Suspension System

设计了2种结构形式的车用蓄能悬架,建立了车辆蓄能悬架系统的数学模型,构建了Ⅰ、Ⅱ型蓄能悬架结构,采取多目标优化方法,得到了2种蓄能悬架的性能参数,在仿真基础上,进行了台架试验,仿真与试验结果较为一致,表明蓄能悬架系统充分发挥了弹簧相位滞后、阻尼器呈中性及蓄能器相位超前的特性,提高了车辆隔振能力,协调了整车综合性能。

Two types of suspension with inerters were designed. The mathematical model of suspension with inerters was built. The suspension with inerters of Ⅰ and Ⅱ types 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.
