Abstract

Abstract

The vibration performance of mechanical equipment is closely related to the impedance characteristics of the installation infrastructure, and the thickness of the structural plate is one of the important factors affecting the impedance characteristics of the structure. In this paper, for the typical plate and shell installation infrastructure of marine mechanical equipment, by studying the influence law of the thickness of the structural plate on the impedance characteristics of the structure, it is found that only the thickness of the bearing surface and bottom surface of the structure has a significant impact on the impedance characteristics of the structure, but the thickness of the supporting surface does not. Therefore, the basic method for the simulation design of the impedance characteristics of the structure is obtained. According to this method, the impedance characteristic simulator of the structure is designed, and the impedance characteristic test is carried out. The test results show that the impedance characteristic of the structural simulator is close to that of the actual structure, which verifies the effectiveness of the design method.
