摘　　要：基于均匀等截面Ｂｅｒｎｏｕｌｉ－Ｅｕｌｅｒ梁的横向自由振动精确解，采用状态变量描述法，提出了一种求解非均质阶梯梁横向自由振动精确解的新方法．文中给出了实际算例，并对其结果进行了分析比较．Based on the accurate solution for free vibration of Bernoulli Euler Beam with uniform cross section,a new method to obtain the accurate solution of free vibration problems of nonhomogeneous stepped beam is proposed by means of the state variats.An example is given and the results are compared with the one presented in other paper.

关 键 词：阶梯梁 横向自由振动 非均质阶梯梁 精确解
