车辆转向梯形优化设计及其求解方法的研究

The optimal design of steering trapezoidal mechanism of vehicles and the research of solution method

在现有文献研究的基础上,对车辆转向梯形优化设计模型的求解方法进行了探讨。通过对该模型的研究分析,用一般方法求解该模型,计算速度偏慢且容易陷入局部最优解。通过对实数遗传算法进一步研究,提出了一种改进算法。结合轮式车辆转向梯形机构的实例计算并与一般方法计算比较,证明该方法不仅可提高运算速度,而且增大了求得全局最优解的可能性。

Based on the present literatures, this article has carried on the discussion to the vehicles steering trapezium optimization design model solution method. Through to this model research analysis, solves this model with the general method, the computation speed slow also is easy to fall into the partial optimal solution. Through to real-coded genetic algorithm is further researched, and an improved method is proposed.Through the combination of wheeled vehicles to the steering trapezoid and with the examples of the general methodology of comparison, proven not only increase calculating speed, but also improve the possibility of seeking the whole optimal solution.
