| 摘 要： | 由实心圆杆的扭转波的控制方程展开讨论,在假定横截面保持平面且运动是绕其轴的转动的条件下导出转角的波动方程。通过与杆的纵振动波动方程与弦振动的一维波动方程中各个量的物理意义进行比较分析,得出扭转波是纵波的结论。并从纵波和横波的物理和数学性质方面加以比较,验证所得结论。

| Abstract: | Physics and mathematics method is used to study the control equation of twisting wave of solid cylindrical bar. This paper analyses the wave equation of the angle of rotation under assumption that the cross-section remains plane and keeps rotating. The result demonstrates that the twisting wave is longitudinal wave by anglicizing physical meaning of the longitudinal wave equation, transverse wave equation, and twisting wave equation. Comparing with the physical and mathematic feature of the longitudinal wave and transverse wave, polarization and superimposition, certificates this conclusion. |
