摘要: 为预测高速履带车辆制动系统能量与制动力的分布规律,以某型履带车辆为例建立其整车动力学模型、推进系统模型以及制动系统模型,提出一种由路线长度、坡度、半径、侧倾角、路面功率谱密度、行驶阻力系统. 土壤最大附着系数、最大转向阻力系数8个参数定义试验场地的建模方法。分析了道路参数对车速的影响;采用最优控制理论设计车辆最短时间仿真行驶策略,基于试验数据建立二元线性回归方程修正仿真制动转矩。通过试验与仿真验证了模型的准确性以及控制策略的有效性。基于1 000 km试验数据建立典型试验场地模型,并预测了6 000 km车辆全寿命里程制动能量与制动力分布情况。仿真与预测结果验证了该方法的可行性。

Abstract: A series of models, including a dynamics model, a driving system model and a braking system model, were established to study a tracked vehicle, which are used to predict the energy/force distributions of the braking system in high speed tracked vehicle. An approach to define testing road using eight parameters such as line length, slope, radius, roil angle, pavement power spectral density, running resistance coefficient, maximum soil adhension coefficient, and maximum steering resistance coefficient, is proposed, and then the influences of these parameters on the speed of vehicle are investigated. A driving strategy to minimize the running time of vehicle is designed based on the optimal control theory, and a binary linear regression equation used to calculate the braking torque is derived statistically. The accuracy of the approach and the efficiency of the strategy are verified using the experimental and simulated results. A typical model is built based on the experimental data of 1 000 km distance field test, and is used to predict the energy/force distributions of braking system in the region of a whole distance of 6 000 km.
