摘　　要：针对履带环上复杂的履带张紧力问题,研究了张紧力在履带环上的分布情况,并分别以诱导轮、上支履带、主动轮及负重轮为隔离体,分析履带张紧力与外部载荷的关系.在此基础上,建立了履带环张紧力分布的理论估算模型.利用多体动力学模型,对不同路面障碍下的履带张紧力进行了理论估算和动力学仿真,通过对理论估算与仿真结果的对比分析,检验了履带环张紧力估算模型的合理性.Aiming at the complex track tension of track link,the distribution of track tension on track link was studied,and the relation of track tension and outer loads was analyzed depend on the free body diagram of the idler,upper track,sprocket,and road wheels.A theoretical estimation model of track tension was built based on these analyzed results;and the track tension in different road blocks was simulated with a multi-body dynamic model.Comparing the theoretical estimation results with the simulation results,the rationality of the theoretical model was validated for track link tension.
