针对大型履带式液压凿岩台车原地转向能力展开研究。以车辆-地面力学理论、履带车多刚体建模理论为基础，在多体动力学软件 RecurDyn 中构建了整车的动力学模型，分析了三种路面条件下履带式车辆的结构参数即履带接地长度与履带中心距比值L/B对转向能力的影响。仿真结果表明，结构参数L/B对履带式车辆的转向能力有很大影响；履带车辆在软地能够转向必须满足L/B小于1.7，且当L/B越小，履带车转向能力更好；对于在硬地转向，L/B越小，履带车辆转向稳定性更好。仿真结果与理论分析相符合，互为验证，研究工作对大型履带车辆行驶操控和结构优化设计提供了新思路。
針對大型履帶式液壓鑿巖檯車原地轉嚮能力展開研究。以車輛-地麵力學理論、履帶車多剛體建模理論為基礎，在多體動力學軟件 RecurDyn 中構建瞭整車的動力學模型，分析瞭三種路麵條件下履帶式車輛的結構參數即履帶接地長度與履帶中心距比值L/B對轉嚮能力的影響。倣真結果錶明，結構參數L/B對履帶式車輛的轉嚮能力有很大影響；履帶車輛在軟地能夠轉嚮必鬚滿足L/B小于1.7，且噹L/B越小，履帶車轉嚮能力更好；對于在硬地轉嚮，L/B越小，履帶車輛轉嚮穩定性更好。倣真結果與理論分析相符閤，互為驗證，研究工作對大型履帶車輛行駛操控和結構優化設計提供瞭新思路。

We do research on the pivot turning ability of large hydraulic crawler jumbo. Based on the vehicle terramechanics theory, tracked vehicle multi-rigid body modeling theory, the dynamic model of vehicle is built in the multi-body dynamics software RecurDyn. We analyze the influence of the structure parameters of the tracked vehicle, which is the ration between track ground length and track center distance L/B under three kinds of road conditions. Results indicate that structure parameter L/B has great influence on the steering ability of tracked vehicles. L/B less than 1.7 is necessary for steering of tracked vehicles and steering ability is better. L/B is less and steering stability steering on hard road is better. The simulation results are compatible with the theoretical analysis. We provide a new idea for drive control and structure optimization design of large tracked vehicle. We also provide a theoretical basis and an effective solution for driving property’ further research of large tracked vehicle.
