摘要
以连接螺钉预紧力对换能器的振动特性影响规律为研究对象,对换能器进行动力学仿真,其中系统谐振频率经采用阻抗分析仪扫频测试,实际振动模态采用多谱勒测振仪对键合工具进行多点速度扫描,测试结果与仿真数据相符。
A transducer′s vibration characteristics influenced by parameters such as the pre-stress of a bolt are studied in detail.The finite element model of the ultrasonic transducer is built.Based on the model,its frequency and its vibration model are analyzed.Theoretical results are verified by experiments.
