摘要: 针对多轴线矿用车自重大、工作路况复杂恶劣、轮胎磨损消耗大的特点,提出可切换转向模式的矿用车转向系统,并建立280 t矿用车多轴线转向机构的参数化模型。提出基于“当量理论转角”的多轴线矿用车转向系统优化设计方法,分析不同转向模式转角误差协同优化设计的可行性,协调匹配不同转向模式下的各轮转角误差。研究结果显示,优化后转向机构八字转向总体性能优于常规转向模式,与原始设计相比更加符合车辆运输工况的实际需求,优化目标加权当量转角误差值由优化前的3.021下降为2.550,下降幅值为15.57%,说明整体效果比较明显。研究结果对于设计多轴线车辆转向系统具有重要的指导意义和参考价值。

Abstract: Aiming at the characteristics of high weight, complex and harsh working conditions, and high tire wear and consumption of multi-axis mining vehicle, a mining vehicle steering system with switchable steering modes is proposed, and a parameterized model of multi-axis steering mechanism of the 280 t mining vehicle is established. A multi-axis mining vehicle steering system optimization design method based on “equivalent theoretical turning angle” is proposed to analyze the feasibility of coordinated optimization design for different steering angle errors, and the wheel angle errors under different steering modes are coordinated matching. The research results show that the overall performance of the optimized steering mechanism’s figure-sharing steering is better than that of the conventional steering mode. Compared with the original design, it is more in line with the actual needs of vehicle transportation conditions. The weighted equivalent turning angle error of the optimization target is reduced from 3.021 to 2.550. The decline was 15.57%, indicating that the overall effect is relatively obvious after the optimization. The results have significant reference value for the design of multi-axis vehicle steering system.
