摘　　要：为了探索车辆可控ISD(inerter-spring-damper)悬架的实现形式与隔振潜能,提出一种液电耦合式车辆可控ISD悬架系统。首先,介绍新型液电惯容器的基本结构和工作原理,以车辆1/4悬架模型作为研究对象,搭建液电耦合式车辆ISD悬架的动力学模型。然后,以提升悬架综合性能为控制优化目标,设计基于液电惯容器的车辆ISD悬架单神经元PID控制器,应用多目标遗传算法对控制参数进行优化求解,在随机路面输入条件下仿真分析液电耦合式车辆可控ISD悬架的隔振性能。最后,研制新型液电惯容器试验样机,并搭建液电耦合式车辆可控ISD悬架试验台架,基于dSPACE进行半实物仿真试验。研究结果表明:与传统被动悬架相比,液电耦合式ISD悬架的车身加权加速度均方根下降了7.8%,悬架动挠度均方根下降了13.8%,悬架综合性能得到显著改善,为车辆可控ISD悬架的研究提供新思路。To explore the realization form and vibration isolation potential of vehicle controllable inerter-springdamper(ISD)suspension,a hydro-electric coupling vehicle controllable ISD suspension system was proposed.Firstly,the basic structure and working principle of the new type of hydro-electric inerter were introduced.Taking a quarter of suspension model as the research object,the dynamic model of the hydro-electric coupling vehicle ISD suspension was constructed.A single neuron PID controller of vehicle ISD suspension based on hydro-electric inerter was designed,and the control parameters were optimized by multi-objective genetic algorithm.The vibration isolation performance of the hydro-electric coupling vehicle ISD suspension was simulated and analyzed under random road input.Finally,the test prototype of hydro-electric inerter was developed,and a hydro-electric coupling vehicle controllable ISD suspension test bench was established.The hardware-in-the-loop simulation test was carried out based on dSPACE.The results show that compared with passive suspension,the body weighted acceleration root mean square(RMS)of the hydro-electric coupling ISD suspension decreases by 7.8%,and the dynamic deflection RMS of suspension decreases by 13.8%,and the comprehensive performance of the suspension is significantly improved,which provides a new idea for the research of vehicle controllable ISD suspension.
