The Application of Dynamic Finite Element Method in Beam Structure
When the practical problem is solved based on finite element method, researchers are often transformed dynamic problem into static one in order to simplify calculation, which brings to large error generally. FEM is good method in solving dynamic characteristics of structure by using only drawings, project and related experienced knowledge. By analyzing the similarities and differences between static FEM and dynamic FEM and discussing their basic principles, the calculation results of static and dynamic FEM are discussed according to the example of simply supported beam with simple harmonic excited force in its midpoint position. The results show that dynamic finite element method has higher solution precise than static one in dealing with practical dynamic problem.
