【摘要】:超聲振動系統(tǒng)傳統(tǒng)的設(shè)計方法普遍存在計算量大且精度不高的缺陷。在設(shè)計過程中引用有限元分析軟件ANSYS Workbench對換能器、變幅桿和工具頭等進行靜力、模態(tài)、諧響應(yīng)的模擬分析,得出了各部分最大、最小的位移和應(yīng)力值出現(xiàn)的部位以及諧振頻率的大小,對不合理的設(shè)計尺寸進行優(yōu)化和修正。最終確定了換能器的尺寸和預(yù)緊力大小,變幅桿放大系數(shù)為2.36,阻抗為8Ω;工具頭放大系數(shù)為1.27,端面最大振幅為5.5μm。將設(shè)計的超聲振動系統(tǒng)應(yīng)用到超聲輔助振動拉伸、壓縮試驗中,當載荷為10 k N時,振幅為5.4μm,僅衰減1.8%。
[Abstract]:The traditional design methods of ultrasonic vibration system generally have the defects of large calculation and low precision. In the design process, the finite element analysis software ANSYS Workbench is used to simulate the static, modal and harmonic response of transducer, amplitude lever and tool head. The maximum and minimum displacement and stress values of each part and the magnitude of resonance frequency are obtained, and the unreasonable design dimensions are optimized and corrected. Finally, the size and pretightening force of the transducer are determined. The magnification factor of the horn is 2.36, the impedance is 8 惟, the magnification factor of the tool head is 1.27, and the maximum amplitude of the end face is 5.5 渭 m. The designed ultrasonic vibration system is applied to the ultrasonic assisted vibration tension. When the load is 10 KN, the amplitude is 5.4 渭 m and the attenuation is only 1.8 渭 m.
