MODELING AND SIMULATION OF AN AUTOMATIC BALANCE OSCILLATOR MECHANISM BASED ON ANSYS

In order to solve the problem of vibration caused by unbalance dynamic, and optimize certain parameters to improve the balance adjustment device of thermostatic oscillator, this paper introduces a method to simulating the modal of the core components of thermostatic oscillator. By using the finite element software ANSYS Workbench, we obtain the natural frequencies and mode shape maps. And then comparing with the frequencies which balance blocks in different angles, we find that if the machine load remains constant, the change of the center of mass will have little effect on the modal frequency.
