摘　　要：在Adams/Car创建双叉臂前悬架的虚拟样机模型,并进行仿真实验;将Adams集成到Isight中,进行灵敏度分析,获取对悬架性能参数影响较大的悬架硬点坐标。以此作为设计变量,以悬架的运动学性能作为响应,拟合得到几种不同的近似模型。利用Nsga-II遗传算法进行优化,得到优化的悬架尺寸参数。使得悬架运动性能得到提高。A approximation model and a genetic algorithm are adopted to determine the best dimension parameters of the large mining truck.This study creats virtual prototype models of the front suspension of double wisebone and conducts simulation tests.This study intergrates Adams to obtain the suspension hardpoints(shown as the coordinates in 3D space),which have great impact on parameters of suspension performance,by performing sensitivity analysis.Then,several different approximation models can be obtained by taking the coordinates as design variable and echoing with suspensions'kinematics character.This study acquires the optimized suspension dimension parameters by applying Nsga-II genetic algorithm.Kinematic performance of suspensions can be improved eventually.
