摘要
本文基于多轴电控辅助转向的某全地面起重机,建立多轴转向系统的动力学模型,对纵向转向机构和单桥转向梯形进行优化设计;通过设定目标函数进行参数优化,将各轮实际转角与阿克曼理论转角的偏差控制在1.0°以内,从而保证各轮在行驶转向过程中作纯滚动,有效的避免因滑移造成的轮胎偏磨。
This thesis based on Truck Crane with multi-axles electrohydraulic auxiliary steering system.Using dynamics simulation soft to establish multi-axles steering system model,then design and optimization trapezoidalrod system of the axle and longitudinal rod system between different axles;through optimization parameters and giving target function,controlling the deviation of each Axle between actual angle and ideal theory angle beyond 1 degree,which can guarantee all of tires rolling around one center during turning process to avoid tires’wear and tear effectively.
