摘　　要：为解决履带式全地形车辆舒适性及抗冲击性能差的问题,提出一种含弧弹簧阻尼结构的扭转减振器式悬架系统,设计了单负重轮悬架系统并开展动力学建模与舒适性分析,研究了不同工况下整车舒适性及抗冲击性能。研究发现:①单负重轮悬架系统静、动态特性参数值均在合理的范围内;相同路面车速增加时,单负重轮悬架系统车身垂向加速度和悬架动挠度均方根的相对增长率降低;路面等级、车速增加时,单负重轮悬架系统车身垂向加速度传递率(8.5%~6.5%)以较小的数值呈小幅下降趋势。②整车通过D、E级路面和极端路面时,所提悬架系统相对传统扭杆弹簧悬架系统表现出优良的舒适性和抗冲击性,验证了悬架设计方案的正确性和有效性。Here,to solve the problem of poor comfort and impact-resistance of crawler type all-terrain vehicles,a torsion vibration damper type suspension system with arc spring damping structure was proposed.A single load wheel suspension system was designed to perform dynamic modeling and comfort analysis and study the overall vehicle comfort and anti-impact performance under different working conditions.The study showed that①static and dynamic characteristics parameter values of the single load wheel suspension system all are within a reasonable range;when the vehicle speed increases on the same road surface,the relative growth rate of RMS values of vehicle body vertical acceleration and suspension dynamic deflection decreases;when the road level and vehicle speed increase,the vertical acceleration transmissibility(8.5%~6.5%)of the single load wheel suspension system’s vehicle body exhibits a slight downward trend with smaller values;②when the full vehicle passes through D and E grade road surfaces and extreme road surface,the proposed suspension system exhibits excellent comfort and anti-impact performance compared to traditional torsion bar spring suspension systems to verify the correctness and effectiveness of the suspension design scheme.
