摘　　要：建立了解梁振动问题的拟小波-精细时程积分方法.利用拟Shannon小波对空间域进行离散,将问题转化为常微分方程组,然后用精细时程积分法对其求解,得到了求解梁振动问题一个有效的数值方法,数值算例表明该方法具有较高的精度.The Quasi wavelet-precise integration method for solving the vibration problems of beam is established.The spatial domain is discreted by using the quasi Shannon wavelet,the problem is transformed into ordinary differential equations,and then the precise time-integration method is used to solve the equations,an efficient numerical method is obtained to deal with the vibration problems of beam.The numerical examples show that the method is better.
