根据技术要求和基本技术参数,运用解析法对糖果包装机的推糖机构进行了结构分析,运用封闭矢量法对推糖机构中的曲柄摇杆进行运动学理论计算,利用Adams 软件进行建模与仿真分析。在分析基础上运用Ad-ams 进行优化,以压力角最小为目标函数,以曲柄摇杆的长度关系和摇杆转角24. 4°为约束条件,以曲柄长度、连杆长度、摇杆长度为设计变量,得到设计变量最优解。

According to the technical requirements and basic technical parameters, structural analysis of feeding mechanism of candy packaging machine was carried out using analytical method. Kinematics of crank rocker of the feeding mechanism was calculated theoretically using closed vector method. Modeling and simulation analysis was carried out using Adams software. Optimization was carried out using Adams software based on analysis. Optimal solution of design variables were obtained using minimum pressure angle as the objective function, the length relationship between crank and rocker and rocker angle 24. 4°as the constraints, and crank, rocker, crank angle as design variables.
