摘　　要：在高档纸盒的内盒成型工位设计了一种用于长方形纸板围条折弯的八杆机构,对其进行了理论分析与仿真,验证其是否能达到纸盒成型过程中形成两面折弯角的目标。基于平面连杆机构运动学原理与动力学原理,对机构进行分析,得到机构的运动学模型和动力学模型;结合实际工况,运用Adams软件对机构进行了仿真;得到关键构件的位移、速度与加速度方程和构件的动态静力学方程,以及关键构件的位移、速度、加速度和理想状态下与含间隙转动副条件下的力曲线。仿真得到的曲线分析结论符合设计要求且提供了一定的参考性,从而验证了折弯八杆机构的确定性。In the inner box forming station of the high-end carton,an eight-bar mechanism for bendingrectangular cardboard strips is designed,and a theoretical analysis and a simulation are carried out to verifywhether it can achieve double-sided bending during the carton forming process. Based on the kinematic and dy-namic principles of the plane linkage mechanism,the mechanism is analyzed,and the kinematic model and dy-namic model in the mechanism are obtained;combined with the actual working conditions,the mechanism issimulated by Adams software. The displacement,velocity and acceleration equations of the key components andthe dynamic statics equations of the components,as well as the displacement,velocity,acceleration and theforce curves of the key components in the ideal state and under the condition of a rotation pair with clearance areobtained. The curve analysis conclusions obtained by the simulation meet the design requirements and provide acertain reference,thus verifying the certainty of the eight-bar bending mechanism.
