从波动方程出发,对余弦型变幅杆的扭转振动进行了系统探讨。利用传统方法,推导出了“余弦型变幅杆”扭转振动的频率方程和各特性参数表达式,为余弦型扭转振动变幅杆的设计提供了一定的理论依据,对巳有阶梯型、锥型、指数型杆的结果是一个完善。
The frequency equation and the expressions for calculating the parameters of the cosine horn are derived based on the wave equation of variable cross-section horn in torsional mode. This provides theoretical basis for designing and calculating cosine horn in torsional mode.
