摘要
为研究履带车辆在随机环境下的行驶载荷,利用解析法和响应面相结合的方法,建立了履带车辆转向载荷替代模型,并采用蒙特卡洛抽样方法,分析了统计情况下车速、摩擦因数和行驶阻力系数对驱动力矩和制动力矩的影响,最后通过实车试验对计算结果进行了统计验证。结果表明:计算结果与试验结果统计分布一致,证实了所提方法的科学性,为履带车辆在复杂随机环境下行驶载荷的统计计算提供了新的途径。
To study the driving load of tracked vehicles in stochastic environment,a superseded model of steering loading is built by using response surface and analytic method. Based on this superseded model,effects of statistical vehicle velocity,friction coefficient and motion resistance coefficient on traction and braking torques by means of Monte Carlo are analyzed. A certain tracked vehicle is tested at last and testing results are statistically analyzed. The scientificity of the method are verified with the coincidence of the computing results and testing result,which puts forward a new way to calculate the driving loading in complex stochastic environment.
