摘要：

为了提高低塑性轻量化板材接头的连接质量、降低成形力、避免连接过程中产生裂纹缺陷，提出了摩擦铆压塑性连接工艺，并设计了交流伺服塑性连接设备。利用ANSYS Workbench软件对设备的机身进行了静力学分析，校核了机身刚度和强度，并通过模态分析研究了设备振动响应特性。结果表明：该设备每个自由度的运动均由单独的交流伺服电机驱动控制，传动链短、结构紧凑，主轴可提供120 kN下压力。机身竖直方向的最大变形量为0.074 mm，最大累积变形量为0.16 mm，水平方向最大变形量为0.011 mm，最大累积变形量为0.38 mm，机身的强度与刚度均满足摩擦铆压塑性连接工艺需求。机身各低阶模态频率均避开了设备、电机和减速器的工作频率，设备工作过程中振动稳定，不会发生共振现象。最后，在该设备上开展了铝合金板材的摩擦铆压连接试验，所获铝合金板材的摩擦铆压连接接头，背面光滑平整，证明了所设计的交流伺服塑性连接设备的结构和功能均能满足摩擦铆压塑性连接工艺的需求。

In order to improve the connection quality of low-plasticity and lightweight sheet joints, reduce the forming force and avoid causing crack defects during the connection process, the friction assisted clinching (FAC) plastic connection process was proposed, and the AC servo plastic connection equipment was designed. Then, the statics analysis of fuselage for the equipment was conducted by software ANSYS Workbench to check its stiffness and strength, and the vibration response characteristics of the equipment were studied by modal analysis. The results show that the movement of each degree of freedom for the equipment is driven and controlled by a separate AC servo motor, the transmission chain is short and the structure is compact, and the main shaft can provide 120 kN down force. For the fuselage, its maximum deformation amount in the vertical direction is 0.074 mm, and its maximum cumulative deformation amount is 0.16 mm, while its maximum deformation amount in the horizontal direction is 0.011 mm, and its maximum cumulative deformation amount is 0.38 mm, so the strength and stiffness of the fuselage meet the requirements of FAC plastic connection process. Furthermore, the low-order modal frequencies of the fuselage avoid the working frequencies of equipment, motor and reducer, the vibration is stable during the working process of the equipment, and no resonance phenomenon occurs. Finally, the FAC connection test of aluminum alloy sheet was conducted on the equipment. And the back surface of the joint obtained for aluminum alloy sheet by the FAC connection process is smooth and flat which proves the structure and function of the designed AC servo plastic connection equipment can meet the requirements of the FAC plastic connection process.
