摘要：
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. © 2023 Chinese Vibration Engineering Society.
