Abstract
To verify the mechanical stability of the electronic equipment rack mounted on domestic naval ships, the developing electric equipment rack should pass the mandatory test procedures, namely MIL-STD-167-1A and MIL-S-901D for vibration and shock, respectively. The criterion for the two harsh tests is no abnormality for the mounted electronic equipment and no damage to the mechanical rack structure. In this study, a verification method for the naval ship’s electronic equipment rack was proposed to verify the structural robustness during the two harsh test situations. The feasibility of the structural robustness was first evaluated using the finite element model of the electronic equipment rack for the two test cases and then, bench tests were conducted on a prepared prototype according to the speculated test regulations, for both MIL-STD-167-1A and MIL-S-901D. The test results showed that the prepared prototype exhibits structural robustness during the two test procedures.
