摘要
以VP6型高速插秧机为研究对象,在硬地和水田两种路面条件下对其进行了转弯半径测量试验,获得了不同转向角度下的转弯半径数据。同时,基于阿克曼转向原理和高速插秧机几何外形参数,计算出该插秧机理论转弯半径,将测量数据与理论数据进行了对比分析,并引入侧偏模型对高速插秧机转弯半径的内在规律进行研究。研究结果对于插秧机转向系统的优化设计与转弯过程中控制系统算法编写具有一定的参考价值。
The VP6 high-speed rice transplanter is taken as research object. Its steering radiuses are measured on hardstand and paddy field and the steering radius data with different steering angles are acquired. The theoretical steering radiuses of rice transplanter are calculated based on Ackerman principle and its geometrical parameters. The measuring data and theoretical data are compared and then the internal laws of steering radiuses of high-speed rice transplanter are analyzed by introducing cornering model. The research results have a good significance for optimizing steering mechanism and writing control system algorithm.
