| 摘 要： | 本文讨论了变截面传振杆力阻抗分布和谐振条件.指出在求解变截面传振杆谐振条件时,除应考虑平面波传播时的轴向力阻抗分布外,还必须考虑由于截面变化引起的轴向剪切力及波阻抗反射的影响.

| Abstract: | The study shows that for solving the resonant condition of high intensity vibrating pole, the influence of the reflection of the wave impedance due to varying cross-section area must be considered in addition to the axial mechanical impedance distribution based on ideal condition of the pulse wave travel. For several typical vibrating poles of the varying cross-section area, the expressions of the mechanical impedance distribution and resonant condition have been given respectively. And the transcendental equations of the impedance resonant are simplified to approximate algebraic equations. |
