【摘要】 为进一步提升应用机电惯容器的车辆悬架隔振潜能，基于桥式电网络结构，建立车辆机电惯性悬架的四分之一动力学模型，推导机电惯容器的输出力表达式。根据桥式网络阻抗的求解方法，选取三种基础的桥式网络结构与其对应的串并联网络结构进行对比，分析结果显示，在同等元件数量下，桥式网络相较于串并联网络可实现更高阶次的阻抗传递函数。以提升车辆悬架综合性能为目标，采用模式搜索法得到了几种不同结构的车辆机电惯性悬架最优参数。在随机路面下的仿真结果表明：在相同元件数量下，采用桥式网络相较于采用串并联网络的车辆机电惯性悬架具有更好的隔振效果，为应用机电惯容器的车辆悬架系统设计提供新的方法指导。更多还原

【Abstract】 In order to further enhance the vibration isolation potential of vehicle suspension using a mechatronic inerter, a quarter dynamic model of vehicle mechatronic inertial suspension based on a bridge electrical network structure was established, and the output force expression of the mechatronic inerter was deduced. According to the solution method of bridge network impedance, three basic bridge network structures were selected and compared with their corresponding series-parallel network structures. Analysis results show that under the same number of components, the bridge network can realize higher order impedance transfer function than the series-parallel network. Aiming at improving the comprehensive performance of vehicle suspension, the optimal parameters of several different structures of vehicle mechatronic inertial suspension were obtained by a pattern search method. The simulation results under random road surface show that, with the same number of components, the bridge network has better vibration isolation effect than the vehicle mechatronic inertial suspension with series-parallel network, which provides a new method for the design of vehicle suspension system with mechatronic inerter.更多还原
