In a random vibration test of a safety control equipment, the acceleration response is too large to satisfy the work requirement, and hence an improved design study is executed in this paper. Firstly, based on random analysis, a vibration control structure is designed from the aspects of strength and damping. The results indicated that the vibration structure can satisfy the design requirement. In the end, the structure is produced and tested. The conclusion is that the error between the results of finite element analysis and test is small, and the improved design structure can satisfy the work requirement.
