摘　　要：结合汽车敞篷机构具体设计需求,以软顶敞篷折展机构作为研究对象,从4-8构件单自由度机构运动链中拟定出瓦特I型6杆机构作为敞篷折展机构的型。基于Burmester理论,根据运动任务的拆解,利用几何综合过程,确定出机构中各构件的尺度。在此基础上,结合机构简图尺寸进行结构建模,对存在运动干涉问题的构件进行结构优化。依据结构优化结果,进行样机试制,实验结果符合设计需求。This paper will combine the design needs of automobile convertible mechanisms,take the convertible mechanism of the soft top convertible as the research object.From the kinematic chain of single DOF mechanism with 4-8 links,Watt I type 6-bar linkage is proposed as the type of convertible mechanism.Based on Burmester theory,according to the disassembly of motion tasks,the dimensions of each link are determined by using the geometric synthesis method.On this basis,the structural model is carried out in combination with the dimensions of the linkage,and the structural optimization of the link with motion interference problems is carried out at the same time.According to the structural optimization results,the prototype is trial produced,and the experimental results meet the design requirements.
