摘要：

The computing method of non-uniform structure was study. The FEM format based on non-uniform equivalent beam was proposed. And the stiffness matrix based on FEM format was deduced. Moreover, through comparing with the results of FEM, the maximum error between them was about 11.1% so as to verify the accuracy of FEM format proposed. The study in the paper provides a new computing method and basis for design and calculation of similar non-uniform mechanical structures.
