摘要
文章根据水陆两栖车辆的车轮收放装置的特点,建立改进型双横臂独立悬架的静力学和运动学模型,运用小生境遗传算法,在MATLAB中开发了多目标的优化程序,通过高次迭代排除干涉项,求取到了全局最优解。并进一步在ADAMS中建立悬架的运动学模型,验证其优化设计的可行性,仿真分析表明,优化后的结果达到悬架设计的性能指标,是一种水陆两栖车辆车轮收放装置中悬架系统的有效设计新方法。
The statics model and dynamics model for the improved-double-wishbone independent suspension guide mechanism and deployed for the amphibious vehicle are established, according to the characteristics of device＇s retracted. Using the niche genetic algorithm, a multi-objective optimization program in MATLAB to verify the feasibility of the solution after the high iteration. Tthe global optimal solution was obtained. A kinematics model in ADAMS is made. The results achieved the design performance index of the suspension. An effective method to design the suspension system obtained.
