Simulation Results

The monostable acoustic metamaterial is realized by placing a flexible panel with a magnetic proof mass in a symmetric magnetic field. The theoretical model of monostable metamaterials has been proposed. The method of finite element simulation is used to verify the theoretical model. The magnetic force of the symmetrical magnetic field is simplified as the relationship between force and displacement, acting on the mass. The simulation results show that as the external magnetic force increases, the peak sound absorption shifts to low frequencies. The theoretical and finite element simulation results are in good agreement.

Load Displacement

The software ABAQUS is used to perform the finite element simulation of a group of reinforced concrete beam tests. The load-displacement skeleton curves of the beams are obtained after the completion of the simulation. Test results and simulation results are compared, results showed that the finite element simulation can be more accurately simulate the test situation. Then, the software ABAQUS is also used to simulate different types of reinforced concrete frame beams, and access to load-displacement skeleton curves and moment – rotation curves of the beams. Reference to the advanced performance-based design method, the curve classified according to different factors. The performance parameters of beams are obtained from the curves. Performance parameters can provide quantitative reference index for performance evaluation of beam.

Optimal Design Method

For the difficulty of calculating the size of the Pre-Manufactured hole of flanging, the formula was derived by using the theory of equal line length and the theory of equal area. And the formula was verified by finite element simulation. Due to theoretical formula has certain error, the optimal design method based on interpolation was put forward and optimization design the size of the Pre-Manufactured hole of flanging. Engineering example shows that this optimization design method is accuracy and convergence speed, and it can quickly calculate the the size of the Pre-Manufactured hole of flanging.
