A rotational piezoelectric energy harvester for efficiently harvesting wind energy is developed. The piezoelectric (PVDF) beam generates electricity using the impact-induced vibration. An analytical model is presented and simulated using finite element method. The transient responses of the piezoelectric beam subjected to an impulse pressure are obtained. The relationship between rms output voltage...
Simulation is the important method for shock-resistant ability design of shipboard equipment. And shipboard equipment shock-resistant ability is the one of important factor of ship life ability. Four-missile launcher resistant shock ability has been evaluated by American navy dynamic design analysis method (DDAM). The four-missile launcher has maximal value of displacement at Z direction, and has...
