Modeling and Simulation Research on Electrodynamic Vibration Generators

Finite element modeling was carried out on a certain electrodynamic vibration generator itself.Methods of modeling were introduced.Then the modal was updated and its mode of vibration was analyzed according to the modal test data of the vibration generator.The results show that the finite element modal of the vibration generator embodies its actual dynamic properties that can be used for vibration test simulation.Finally,according to the real conditions of sine-scan vibration test,simulation was accomplished by using the given algorithm.
