摘要
为解决立体织物穿刺成型时采用人工缝合方式存在的问题,设计一种基于双四连杆机构的缝合装置。根据缝合的工艺流程,确定装置上两个勾针的运动轨迹和极限位置,利用解析法求出连杆和勾针的长度。通过建立四连杆机构的运动学模型,推导出两个勾针的位移、速度和加速度公式。在给定运动参数的条件下,应用MATLAB软件仿真得到两个勾针的运动状态和运行轨迹。研究结果验证了该设计的可行性。
To overcome the shortcomings of manual stitching during the puncturing and molding of three-dimensional fabrics,a stitching device based on double four-bar linkage mechanism is designed.The motion track and limit position of the two crochet hooks on the device are determined,and the lengths of the connecting rods and crochet hooks are calculated by the analytical method.By building a mathematical model of the four-bar linkage mechanism,the displacement,velocity,and acceleration formulas for the two crochet hooks are derived.Given the motion parameters,the motion state and orbit of the two hooks are simulated by using MATLAB software.And the feasibility of the design is verified by the research results.
