| 摘 要： | 为改善越野车辆的行驶平顺性,提出一种双气室油气悬架.对双气室油气悬架的结构进行了分析,阐述其工作原理,并建立其数学模型.基于某越野车的参数,建立1/4车辆振动模型,通过仿真分别研究双气室油气悬架的各个参数对其车身加速度、悬架动挠度及车轮相对动载的影响.结果表明,内置蓄能器对车轮相对动载影响大于外置蓄能器;外置阻尼器对平顺性的影响大于活塞上阻尼孔的影响.通过对结果的优化确定了双气室油气悬架的参数,分别在时域和频域内对装有双气室油气悬架、单气室油气悬架以及螺旋弹簧的车辆的平顺性进行了对比.仿真结果表明,与单气室油气悬架和被动悬架相比,采用双气室油气悬架可明显改善车辆的行驶平顺性,更适合于越野车辆.

| Abstract: | In order to improve the ride performance of the off-road vehicle, a twin-accumulator hydro-pneumatic suspension is proposed. Its structure is analyzed, its working principle is described, and its mathematic model is built. Based on the parameters of an off-road vehicle, 1/4 vehicle vibration model is built. Through simulation, the influence of each parameter of twin-accumulator hydro-pneumatic suspension on the vehicle body acceleration, dynamic deflection of suspension and relative dynamic load of wheel is... |
