The Numerical Calculation Tested to Electronic Equipment Cabinet Random Vibrations
The dynamic characteristic and random vibration response characteristic of electronic equipment cabinet were simulated by the finite element analysis software- ANSYS according to the standard and request of mechanical structures for electronic equipment-Tests. First, 3-D finite element model of the cabinet was built. Next, cloud figures of deformation and stress of the model were obtained by loading and it could confirm the maximum of deformation and stress of the cabinet and probability of occurrence within the particular vibration frequency. Last, through more analysis of the frequency response curve, which could confirm harmful consequences random vibrations caused and weak link of the cabinet structure. The research results show that the simulation tests approximate the reality. It provides more convincing evidence for aseismic design and dynamic optimization design in cabinet structure.
