The Vibration Features Analysis on Special Computer

Abstract:

A certain type of special computer was studied as the institute in this paper. Through researching on the structure of the special computer box, use the Pro/E software to create the simplified model of the case, including computer cabinet, PCB, power and fan etc. Model analysis is conducted in the FEA environment ANSYS, attains ten order natural frequency and vibration mode. Dynamic load in the model is applied with half sine impact acceleration, and the resistance performance of the PCB which is the important components of the model is researched by the acceleration, speed and displacement response results obtained. Verify the installation method of vibration isolator can effectively improve the shock resistance of special computer.
