Statics Analysis and Modal Analysis of the Beam Structure of Wave-Maker Based on Finite Element Analysis

In order to achieve lightweighting in the Beam Structure of Wave-maker, it’s necessary to have the statics analyzed for model in the finite element method, results showed that the stiffness and strength have the bigger margin, and it can satisfy design requirements fully, which is the allowable deformation is less than 2 mm, maximum yield strength is less than 325 Mpa. At the same time, in order to get each order modal which the beam, and determine the wave frequency that the need to avoid. Carry on modal analysis of the beam in this paper, results showed that the wave frequency of the wave machine is far less than which each order natural frequency, so the resonance phenomenon caused in the process of work is out of consideration. This research method provides a basis for the design of the beam and optimization.
