Vibration analysis on coupled structure of board and beam

The vibration theory of simple component has been formed well.But in actual engineering,the shape of vibration component is complicated and its vibration theory needs to be analyzed according to the theory of simple shape.A mechanical component is simplified as coupling structure of board and beam according to its shape.Then the equations of board and beam are set up separately.The relation of moment and corner between board and beam is utilized to revise their vibrational equations.At last,theoretical analysis and ANSYS simulations test and revise the theory.At the same time,the two simulation results are compared to prove the correctness of the theory.Through the analysis,a method that can solve the question of vibrational coupling is obtained.
