| 摘 要： | 针对装有油气悬架的车辆在实际应用中所面临的可靠性问题,提出了一种以油气悬架和螺旋弹簧共同作用提供弹性力的复合悬架.结合一种越野车悬架系统参数,给出了复合悬架刚度参数的匹配方法,对复合悬架和油气悬架系统的工作压力、载荷特性及刚度特性进行了对比,并通过仿真进一步对比了其平顺性评价指标.结果表明,复合悬架与油气悬架相比,在降低系统压力,提高可靠性的同时,保证了良好的越野平顺性,更适合于越野车辆.

| Abstract: | Faced with the poor reliability of hydro-pneumatic suspension installed on off-road vehicles,a composite suspension is designed,where the elastic force is supplied by both the helix spring and hydro-pneumatic suspensions.The helix spring and the hydro-pneumatic suspension are used in parallel.The method for composite suspension stiffness matching is proposed based on its use on an off-road vehicle.The working pressure,load characteristics and stiffness characteristics of the composite suspension system are compared with that of the hydro-pneumatic suspension,and the vehicle body vertical acceleration,suspension travel and dynamic load of wheels are compared by simulation.The result showed that the composite suspension is more suitable for using on off-road vehicles than hydro-pneumatic suspension,the composite suspension can reduce the work pressure,improve the reliability,and thus enhancing the riding comfort. |
