摘要

工程车辆铰接式转向结构的突出问题是转向时液压系统存在压力振荡,严重影响转向系统的性能。为解决这一问题,左右油缸的最大行程差和最小最大油缸压力是优化目标,油缸铰点位置是设计变量。采用粒子群优化算法对铰接转向系统进行了多目标优化设计。优化后,转向系统的最大压力降低了 13.5%,振荡幅度降低了 16%,优化效果明显。通过对轮式装载机进行现场转向试验,获得了液压转向系统在压力和流量等不同负载下的动态特性。结果表明,负载对系统的压力响应有重要影响,并确定了压力和流量波动的原因和影响因素。得出了行驶里程与氢耗之间的关系,为车辆控制策略提供了数据支持。高压溢流功耗占总功的 60%,转向器损耗功达 36 kJ。试验结果验证了转向机构优化方法的合理性和正确性,为转向液压系统的改进提供了数据支持。

Experimental Study on Structure Optimization and Dynamic Characteristics of Articulated Steering for Hydrogen Fuel Cell Engineering Vehicles
The prominent problem of articulated steering structure of engineering vehicle is that there is pressure oscillation in the hydraulic system during steering, which seriously affects the performance of steering system. To solve this problem, the maximum stroke difference of left and right cylinders and the minimum maximum cylinder pressure are the optimization objectives, and the position of cylinder hinge point is the design variable. The multi-objective optimization design of articulated steering system is carried out by using the particle swarm optimization algorithm. After optimization, the maximum pressure of the steering system is reduced by 13.5%, and the oscillation amplitude is reduced by 16%, so the optimization effect is obvious. The dynamic characteristics of the hydraulic steering system under different loads, such as pressure and flow rate, are obtained through field steering tests of wheel loaders. The results show that the load has an important effect on the pressure response of the system, and the causes and influencing factors of pressure and flow fluctuation are determined. The relationship between mileage and hydrogen consumption is obtained, which provides data support for vehicle control strategy. The high-pressure overflow power consumption accounts for 60% of the total work, and the work lost on the steering gear reaches 36 kJ. The test results verify the rationality and correctness of the optimization method of steering mechanism and provide data support for the improvement in steering hydraulic system.
