Problems solved by technology

[0002] During the flight of a commercial launch vehicle, the equipment bracket amplifies the vibration caused by aerodynamic noise in magnitude, and then makes the equipment on the rocket withstand the harsh vibration environment, which may cause equipment failure and lead to mission failure.
In related technologies, the traditional "posteriori" vibration environment control method is usually used, which is highly dependent on the ground vibration test. The traditional optimization process adopts the workflow of "empirical design-product production-test verification-design improvement", and The "one-size-fits-all" requirement for the vibration characteristics of the equipment support on the arrow will consume a lot of cost and time to control the vibration and vibration characteristics of the equipment, which cannot meet the needs of low-cost and rapid development of commercial launch vehicles

Abstract

The embodiment of the invention provides a vibration analysis method and system for a carrier rocket equipment support, a terminal and a medium, which relate to the carrier rocket technology. The method comprises the following steps of analyzing vibration characteristics of a to-be-analyzed equipment support through a computer aided engineering method to obtain an analysis result, and performing iterative optimization setting on the equipment support of which the analysis result does not meet the corresponding requirements until the analysis result of the equipment support meets the corresponding requirements.

Description

technical field [0001] The present application relates to launch vehicle technology, in particular to a vibration analysis method, system, terminal and medium of a support for launch vehicle equipment. Background technique [0002] During the flight of a commercial launch vehicle, the equipment bracket amplifies the vibration caused by aerodynamic noise in magnitude, and then makes the equipment on the rocket withstand the harsh vibration environment, which may cause equipment failure and lead to mission failure. In related technologies, the traditional "posteriori" vibration environment control method is usually used, which is highly dependent on the ground vibration test. The traditional optimization process adopts the workflow of "empirical design-product production-test verification-design improvement", and The “one-size-fits-all” requirement for the vibration characteristics of the equipment support on the arrow will consume a lot of cost and time to control the vibrati...
