摘　　要：为解决三角履带脱轮问题,将动力学仿真技术应用到设计中。结合诱导轮、张紧装置、支撑轮、驱动轮等部件的结构,分析了其受力情况,并建立了一类诱导轮张紧装置的动力学模型;同时利用多体动力学软件RecurDyn建立了三角履带车辆的模型,研究了其诱导轮张紧装置的预紧力参数变化对履带张紧力和前端支撑轮垂向位移的影响规律。研究结果表明:适当地增加车辆三角履带张紧装置的压力能够有效地减少支撑轮的垂向位移;计算结果与仿真值的比较结果显示两者基本吻合,说明了该仿真模型的合理性,这为三角履带详细设计阶段各参数的获取提供了参考。Aiming at the problem of wheel＇s falling-off for triangular tracked, dynamics simulation technology was investigated. After the analysis of the stress based on the structure of idler, tension device, supporting the wheel and so on,the tension device＇s dynamic model of idler was established. By using mutibody dynamic software-RecurDyn, the model of triangular track vehicle was developed. Dynamics simulation was established, the influence to tension of the track and the vertical deviation of the anterior supporting wheel through changing the preload parameter of the idler＇s tension device was analyzed. The results show that the vertical deviation of supporting wheel is reduced effectively by increasing prestressing force suitably. The calculated results are compared with the simulation value, which shows they are reasonable. The results can be used as a reference for optimum of the design phase.
