【 摘 要 】

Due to the special structure of the shelter, the cost of trial production and experimentation in the design stage is very high. In order to research the static characteristics of the electronic equipment shelter, the structure of the electronic equipment shelter is discussed. The ANSYS finite element analysis software is used to establish the equivalent finite element model of the overall structure of the electronic equipment shelter and the bearing platform. The static simulation of the body structure under specific working conditions is carried out, and the stress and strain state are obtained. At the same time, the modal superposition method is used to analyse the overall transport vibration response spectrum of the electronic equipment shelter and the bearing platform. The results show that the maximum stress value of the electronic equipment shelter is less than the allowable stress, and the maximum deformation is also in full compliance with the requirements. At the same time, it meets the requirements of the transportation vibration environment adaptability of the electronic equipment shelter, and provides design reference for the similar electronic equipment shelter.
