摘要
针对两端固定弦的强迫振动问题,给出了冲量定理法、按相应齐次问题的本征函数展开法、方程和边界条件同时齐次化法等3种不同的求解方法.并介绍了应用上述3种方法的基本思路和适用条件.
Three methods are introduced to solve the problem of forced oscillation equation with fixation boundary. They are impulse theory method, evolvement on eigenfunction of corresponding homogenized equation, homogenized solution of equation and boundary conditions. The reason for the application of these methods and the time to use them are proposed.
