摘 要: 为实现恶劣路况下某三轴全地形车中、后桥垂直载荷的合理分配,将其中、后桥双横臂独立悬架设计成平衡悬架。本文首先根据拟选结构方案,建立平衡悬架理论模型,推导优化目标函数与设计参数之间关系,使用MATLAB软件编程优化设计变量;然后以优化结果为输入参数,在ADAMS/V iew环境下建立平衡悬架动力学模型,验证设计结果;仿真分析表明该平衡悬架满足中、后桥载荷合理分配要求。 In order to meet the reasonable load distribution between mid & rear axles of all terrain vehicles( ATT) ,A set of equilibrium mechanism among the double wishbone independent suspensions in three-axle ATV were designed. This paper first built the simple model based on the planned sketch of balance suspension, and relate optimization purpose function to design parameters, and optimize design variables using MATLAB language. Then, and the dynamic model of this equilibrium suspension with the optimization results above in ADAMS/View. After simulating and verifying this design. The results prove that the structure can meet the requirements of load distribution.
