摘要
利用非线性材料的本构关系,建立了非线性材料圆杆的扭转固有振动方程,然后采用傅立叶级数法求得了圆杆扭转固有振动的所似解,通过实例计算讨论分析了非线性材料圆杆的扭转固有振动特性。
The natural twist vibration equation is set up by making use of the constitutive relation of nonlinear material. The approximate solution of round rods natural twist vibration is obtained by Fourier series method, and the natural twist vibration character of round rod with nonlinear material is analyzed by calculating concrete examples.
