Abstract:
Based on the analysis of nonlinear geometric characteristics of the suspension systems and tires, a 3D nonlinear dynamic model of a typical heavy truck is established. The impact factors of dynamic tire loads, including the dynamic load stress factors, and the maximal and the minimal vertical dynamic load factors, are used to evaluate the dynamic interaction between heavy vehicles and roads under the condition of random road surface roughness. Matlab/Simulink is used to simulate the nonlinear dynamic system and calculate the impact factors. The effects of different road surface conditions on the safety of vehicle movement and the durability of parts of a vehicle are analyzed, as well as the effects of different structural parameters and different vehicle speeds on road surfaces. The study results provide both the warning limits of road surface roughness and the limits of corresponding dynamic parameters for the 5-axle heavy truck.
基于车辆悬挂系统和轮胎的几何非线性特性分析, 建立了一重型卡车三维非线性动态模型, 采用动态车轮载荷的影响因子即动载荷应力因子、最大和最小垂直动载系数, 对路面随机不平度与重型车辆之间的动态相互作用进行了评价.采用Matlab/Simulink软件对建立的非线性动态系统模型及影响因子进行仿真计算.分析了不同路面条件对车辆行驶安全性和零部件耐久性的影响;同时, 分析了不同结构车辆参数和不同速度对路面的不良影响.研究结果不仅给出了5轴重型卡车运行路面不平度的界限, 也给出了相应动态参数的界限.
