Study on Design Method of Non-Uniform Beam of Mechanical Structure

The non-uniform equivalent beam design method for non-uniform beam of mechanical structure was proposed. Its equivalent mechanical models of tension or compression and bending was established. Moreover, the erro between the result of FEM and the result of non-uniform equivalent beam design method is less than 5% so as to verify the accuracy of non-uniform equivalent beam design method for typical parameter bending cantilever beam and the tension link. The study in the paper provides a new method and basis for design and calculation of similar mechanical structures.
