为适应多种环境需求,提出一种具有串并联切换功能的新型多模式机构。该机构可根据实际工况改变自身的结构约束,从而形成不同的模式,以提高机构的运动适应性。利用螺旋理论对机构的自由度进行分析,并描述了各模式的切换策略;对机构各模式步态进行分析,运用Adams软件对机构步态进行仿真实验,验证了步态的可行性。最后,对机构进行实体建模并讨论了机构的实用性。
In order to adapt to various environmental requirements, a new multi-mode mechanism with series-parallel switching function is proposed. The mechanism can change its structural constraints according to the actual working conditions to form different modes to improve the motion adaptability of the mechanism. The screw theory is used to analyze the degree of freedom of the mechanism and describe the switching strategy of each mode. The gait of each mode of the mechanism is analyzed, and a simulation experiment of the mechanism gait is carried out using Adams software to verify the feasibility of gait. Finally, the entity modeling of the mechanism and the practicability of the mechanism are discussed.
