铰接车转向阻力矩的测定与仿真

Testing and dynamical simulation for the moment of steering resistance of articulated vehicle

对铰接车模型进行了转向阻力矩的测量,在此基础上,利用多体动力学仿真软件RecurDyn建立了轮式铰接车和履带式铰接车仿真模型,得到了整车转向阻力矩曲线。通过比较,对测量结果进行了验证,同时发现履带式铰接车比轮式铰接车原地转向阻力矩小,为下一步折腰转向液压缸的选型奠定了基础。

Firstly the moment of articulated vehicle model steering resistance was tested. On this basis, dynamical analysisand entity modeling of tracked and wheeled articulated vehicle were finished by using the multi - body dynamical simulationsoftware RecurDyn. The curve of resistance moment was obtained and the result was also compared and analyzed. Throughcomparison, the testing result is verified and the conclusion is that the steering resistance moment of tracked articulated ve-hicle is less than that of wheeled articulated vehicle. It provides references for steering cylinder selection.
