Abstract
The vibration and shock of the opto-electronic protective device was induced mechanical failure or fail to work correctly. In order to identify the exciting frequency components of vibration and shock, vibration signals are measured and analyzed from the mechanical power press. In addition, the modal test for the opto-electronic protective device was performed to investigate the dynamic characteristics. Some FEM simulations were carried out and then anti vibration mount was made for opto-electronic protective device. Based on the results of simulations, some kind of rubber mounts were tested to demonstrate the reduction of vibration and shock. It was verified by the test that a considerable amount of vibration and shock were reduced.
