摘要

液力传动工程车驱动时存在车轮偏载现象，影响其运行安全。为此，基于SIMPACK软件建立考虑传动系统的某工程车动力学模型，研究车轮偏载现象随牵引力的变化规律及其对轮重减载率的影响，分析万向轴传递的力矩对左右车轮轮重的影响。同时，基于MATLAB软件建立车轮偏载计算模型进行理论分析，揭示车轮偏载现象形成的机理并对其结构进行改进以降低车轮偏载的程度。研究结果表明：液力传动工程车驱动时存在车轮偏载现象，即一位和四位轮对左轮增载、右轮减载，二位和三位轮对右轮增载、左轮减载；车轮偏载现象使工程车的轮重减载率最大值增大了19.68%，影响该工程车的安全运行；万向轴传递力矩造成车轮偏载，力矩的旋转方向影响轮重增减载的情况，力矩的大小影响车轮偏载的程度；车轮偏载计算模型所得结果与仿真结果吻合较好，充分说明车轮偏载现象分析合理；改进后工程车的轴重转移量几乎无变化，但车轮偏载量最大仅为3.41 kN，相较原模型最大减小了83.57%，轮重减载率最大减小了27.71%，有效降低了车轮偏载的程度。研究结果可为提高液力传动工程车的运行安全提供理论参考。

Abstract

The hydraulic transmission engineering vehicle has the phenomenon of wheel eccentric load in the driving process

which seriously affects its safety. Therefore

a dynamic model of engineering vehicle considering the transmission system is established in SIMPACK software. The variation of wheel eccentric load with driving torque and its effect on wheel load reduction rate are studied. The influence of torque transmitted by cardan shaft on wheel load is analyzed. In addition

the calculation model of wheel eccentric load are established for theoretical analysis in MATLAB software. The mechanism of the wheel eccentric load phenomenon is revealed and the structure is improved to reduce the phenomenon. The results show that when the engineering vehicle is driven

there is the phenomenon of wheel eccentric load. The left wheel load of the first and fourth position wheelsets is increased

while the right wheel load is decreased; The right wheel load of the second and third position wheelsets is increased

while the left wheel load is decreased. The wheel eccentric load phenomenon increases the wheel load reduction rate by 19.68%

affecting the safety of the engineering vehicle. The torque transmitted by the cardan shaft causes the wheel eccentric load

and the direction of it influences whether to increase or decrease of the wheel load. The degree of wheel eccentric load is influenced by the torque transmitted by the cardan shaft. The simulation results are in good agreement with the calculation results

which fully demonstrates the mechanism of the wheel eccentric load phenomenon is reliable. Compared with the original model

the axle load transfer of the improved model has almost no change

but the wheel eccentric load of the improved model is up to 3.41kN

which is reduced by 83.57%

and the wheel load reduction rate is reduced by 27.71%. The improved measure can effectively reduce the degree of wheel eccentric load. The research results can provide theoretical reference for improving the safety of engineering vehicle.
