| Abstract: | By using boundary element method and joint theory, the global machine structure is equivalently modeled by beam elements and spring elements so that a static mechanic model is built up while applying the data provided by machine design drawings for its structural scheme design and predict the static performance of global machine can be predicted at the same time, to provide a basis for modifying the structure. The research results show that the results from the analytical evaluation by the methods presented are close to those from experiments and both the analytical computation precision and efficiency are improved. |
