【摘要】 应用了直线法求解梁振动问题.利用直线法对空间域离散,将问题转化为常微分方程组,然后用四阶龙格-库塔法对其求解,得到了一个求解梁振动问题的有效数值方法.数值算例说明该方法具有较高的精度.更多还原

【Abstract】 In this paper,method of lines is used to solve the vibration problems of beam.The spatial domain is discreted by method of lines,the problem is transformed into ordinary differential equations,and then the fourth-order Runge-kutta 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.更多还原
