摘要以单激励超声椭圆振动复合梁变幅杆为研究对象，基于振动理论，对采用螺钉紧固连接方式加装车刀后的变幅杆进行了数学建模。结合螺钉连接预紧力模型，通过模态及谐响应分析研究了单激励超声椭圆振动变幅杆的车刀端的振动特性。获得了螺钉连接对变幅杆椭圆振动模态及振动传递的影响规律。进而综合螺钉连接预紧力矩变化情况，对不同预紧力矩状态下的变幅杆车刀端进行仿真和试验，分析对比计算值与试验值误差，明确了车刀螺钉连接状况对超声椭圆振动响应的影响。结果表明，车刀螺纹紧固连接主要通过影响弯曲振动来影响系统的纵弯复合谐振；随着车刀连接预紧力矩增大，车刀与变幅杆之间的振动传递损耗减小，超声椭圆振动的弯振传递性能会提升。研究结果可为超声椭圆振动的车刀连接及其整体谐振设计提供依据。

Abstract：Focusing on a combined-beam horn with ultrasonic elliptical vibration, a mathematical model of combined-beam horn with turning tool fixed by screw connection was established based on coupled vibration theory. Integrated with the pre-tightening force calculation model, the vibration characteristics of tool output were analyzed by modal and harmonic response analysis and the law of influence of screw connection on elliptical vibration mode and vibration transmission of horn was inferred. In this model, the vibration states of tool output were gained through simulations and experiments under different pre-tightening forces. The effect of the connection between tool and horn on ultrasonic elliptical vibration was specified after analyzing calculated values and experimental values. It is shown that turning screw fastening connection affects bending vibration state and as the pre-tightening torque of the turning tool increases, the vibration transmission loss between the turning tool and the horn is reduced. Moreover, the transverse bending vibration transmission quality and the overall ultrasonic vibration transmission quality of the system are improved. The research results can provide a theoretical basis for the elliptical vibration of the turning tool connection and its overall resonance design.
