【Abstract】 To solve problems with steering slip and excessive wear of steering wheels, this paper took the steering mechanism as the research object. Based on analysis of the geometric relationship of the mechanism, a mathematical model of the steering mechanism was established and solved to obtain optimized parameters of the steering mechanism by using the least squares method. According to the corresponding parameters, the virtual prototype of the original and the optimized steering mechanism were established, and their steering motions were simulated and analyzed. The results show that the optimized steering mechanism can make the steering of the aerial work platform closer to the ideal state.更多还原
