摘要

摘要: 以机构学中的拓扑图表示方法为基础，分析了常用独立悬架导向机构的拓扑构造特性。依据导向机构的设计需求和限制条件以及机构的过约束特性，以导向运动自由度为目标，构造出一类基本回路数为3的新型独立悬架导向机构的拓扑图，并对其进行了功能结构化设计。在此基础上，运用螺旋理论分析了一种新型导向机构的自由度与过约束特性，根据悬架导向机构的设计需求及空间限制，利用ADMAS软件对这种新型导向机构进行虚拟样机建模，并进行了运动学特性仿真分析。分析结果表明，设计出的新型导向机构满足悬架基本性能要求，间接验证了此设计方法的有效性和可行性。

Abstract: Based on the topological graph in theory of mechanism, the topological characteristics of common independent suspension guiding mechanism were analyzed. According to the design requirements and the over-constraint features of structure, with the freedom of movement for the target, the type synthesis of a class of three loops kinematic chains for independent suspension guiding mechanism was constructed to obtain the required mobility. Then the structural of independent suspension mechanism was carried out. Based on the above results, by using the screw theory, the degree of freedom and over-constraint features of a new guiding mechanism were analyzed. On the basis of the design requirements and space constraints of guiding mechanism, the simulation model of the new type guiding mechanism was established with ADAMS, and kinematics characteristics of the new type guiding mechanism were analyzed. The analysis results show that the new type guiding mechanism meets the requirements of suspension mechanism, it indirectly verifies the feasibility and effectiveness of this design method.
