Abstract

In order to analyze the vibration characteristics of 220kV switch bay mobile load transfer equipment in complex road transportation environment, firstly, according to GJB150.16A-2009 "national military standard of the people's Republic of China - Environmental test methods for military equipment laboratory - vibration test", the power density spectrum of two wheeled trailer with relatively strong excitation in the standard is selected, which can reflect the more stringent environment, and then the vibration test is carried out The three-dimensional simulation model of the equipment is constructed, and the first ten natural frequencies of the equipment under fixed constraints are analyzed by the simulation software. Based on the natural frequency of the equipment and the selected power density spectrum, the random vibration simulation of the equipment is carried out, and the overall structure of the equipment is optimized and improved through the simulation results.
