摘要
文章提出一种基于新型电磁力与液力混合型执行器的馈能型多模式悬架系统,建立了四分之一车辆馈能悬架系统及馈能电路模型,提出了节流阀可调减振器阻尼系数及馈能电路部分参数的计算方法以及采用天棚加地棚的半主动馈能控制策略.仿真结果表明:该控制策略可以改变悬架的舒适性、稳定性及馈能性.试验验证了选取的基本阻尼系数的合理性及仿真模型的准确性,为后续的参数优化及控制算法优化研究提供了基础.
A multi-pattern energy regenerative suspension has been presented based on a new electro-hydraulic actuator.1/4 vehicle energy regenerative suspension system and energy regenerative circuit were built up.A new method is introduced to calculate the energy regenerative circuit parameters and damping coefficient of the absorber,whose throttle aperture is adjustable.This paper also presents a semi-active energy regenerative control strategy by using sky-hook and ground-hook.The simulation results show that the control strategy can change the comfort,stability and energy regenerative ability of suspension.The electro-hydraulic actuator and 1/4 vehicle energy regenerative suspension system has been made.The rationality of the selected basic damping coefficient is verified by the test.The accuracy of the simulation model is verified as well,so that it can be the basic for parameter optimization and control strategy optimization research.
