摘要：
Frame of solar sweeper is complexly welded structure with thin steel plate. A three dimensional model of solar sweeper frame was bullied up in CATIA and finite element mesh was finished in Hypermesh. ANSYS program was applied to modal analysis. Connections and constraints of finite element model(FEM) would be modified through a comparison with modal testing results. It shows that analysis results of distributing tendency and concrete value ranges are coincident well with test results, the max and min error is 1.54% and 8.15% separately. From the results, it could be concluded that accurate dynamic response can be gained based on modified FEM.
