Investigation of Typical Finite Plate Junctions Structures Vibration Performance Based on MPT

並列摘要


The power flow and vibration energy propagation of the plate junction structures with simply support boundary conditions are studied by wave approach. The combination of modal method and traveling wave method is employed to obtain the analytical solution based on Mindlin plate theory (MPT), which take the plate shear deformation and rotary inertia into account. The results have shown that the vibration energy and power flow can be attenuated by the plate junction structures. The plate junction structures type have obvious influence to the power flow results and increase the joint number of plate junction structure will improve the power flow suppressing performance.
