摘要
针对单跨度变刚度梁的横向自由振动问题，利用有限差分法及传递矩阵法并将二者相结合的方法，由该问题的变系数动力控制方程出发，推导出系统频率方程，与已往文献比较，文中算例结果表明，所用计算方法思路清晰，编程简单，计算结果正确。
Considering the free latenal vibration of single span beams with varied rigielity, by the way of combining the finite difference method with transfer matrix method,the frequence equation is driven successfully from the varied parameters dynamic equation in this paper. Comparing with the past references,the caculation method is of clear thinking,simple program and correct results.
