摘　　要：针对MP1040B型模切机肘杆机构中的连杆在使用中破损故障时有发生,在运动学和动力学分析的基础上,利用有限元方法进行了强度分析,结果表明,当在正常模切力2 450 kN时连杆的强度满足要求,当在极限模切力3 136 kN时连杆的强度不满足要求,分析结果为结构的改进或材料的选择提供了依据.The linkage of elbow-bar mechanism is important and easily damage for MP1040B moulding machines.To solve the problem,finite element method based on analysis of kinematics and dynamics was adopted.The result shows that the strength of the linkage is enough when diecutting force is equal to 2 450 kN,however,it is not enough when diecutting force is equal to 3 136 kN.The result can offer important reference for optimization design or selecting new materials of the linkage.
