摘要

基于人体工程学原理,设计了婴儿摇床六杆机构并综合运用Matlab及ADAMS软件实现六杆机构的联合优化设计。建立了六杆机构满足约束条件下求连杆最小长度的方程组,通过Matlab计算出连杆最小尺寸。对机构进行ADAMS参数化建模,设置连杆长度为变量,对机构进行运动学分析和动力学分析,并求出对应点的加速度曲线和连杆受力曲线。结合人体工程学数据,设计出连杆最佳长度、主动杆长度及曲柄转速。研究结论对提高婴儿床的使用功能与舒适性具有实际指导意义。

Abstract

A typical six-bar mechanism for baby bed is designed based on ergonomics,and which is optimized by integrated use the software of Matlab and ADAMS.Under the condition of the six-bar mechanism satisfy the constraints,the equation set for solving the connecting rod minimum length and is built and the connecting rod minimum size is calculated by Matlab.The length of connecting rod is set as a variable,and the parametric model of six-bar mechanism is built by using the software of ADAMS.The kinematics analysis and dynamics analysis of the mechanism are carried out,and the acceleration curve of the corresponding point and the force curve of the connecting rod are drawn out.Combining with the data of ergonomics,the optimal length of connecting rod,the length of active rod and crank speed are designed.The research conclusion have practical instructional significance for enhancing the function and comfortable of the baby bed.
