建立了IC引线键合机的带线夹变幅杆系统的运动微分方程，以及带线夹和不带线夹变幅杆系统的有限元仿真模型，并对仿真模型进行了动态特征参数分析比较，同时，通过试验模态测试结果分析，仿真结果与试验结果相吻合，验证了建立带线夹变幅杆系统的有限元建模是合理的。

英文摘要：

Summarized the theoretical differential equation of structure damp in the wire bonder, the finite element model was set up for the horn system with the wire clamp and without wire clamp in the wire bonding, at the same time modal analysis was performed for them. The result is verified with comparison of data obtained from the test and calculated results obtain from FEM. Good agreement was obtained between the theoretical and experimental results in the horn system with the wire clamp. It is reasonable to set .up the finite element model of the horn system with wire- clamp in the wire bonder.
