Vibration analysis method, device, terminal and medium of launch vehicle equipment support

Abstract

Embodiments of the present application provide a vibration analysis method, system, terminal and medium for a carrier rocket equipment support, which relate to carrier rocket technology. The method includes: analyzing the vibration characteristics of the equipment support to be analyzed by a computer-aided engineering method to obtain an analysis result; performing iterative optimization settings on the equipment support whose analysis results do not meet the corresponding requirements, until the equipment support is set. The analysis results meet the corresponding requirements.

Description

technical field [0001] The present application relates to launch vehicle technology, and in particular to a vibration analysis method, system, terminal and medium for a support of a launch vehicle equipment. Background technique [0002] During the flight of a commercial launch vehicle, the equipment support amplifies the vibration caused by aerodynamic noise by an order of magnitude, and then the equipment on the rocket is subjected to a harsh vibration environment, which may cause equipment failure and lead to mission failure. In related technologies, the traditional "a posteriori" vibration environment management and control method is usually used, which is highly dependent on the ground vibration test. The traditional optimization process adopts the workflow of "experience design-product production-test verification-design improvement", and The "one-size-fits-all" requirement is adopted for the vibration characteristics of the equipment support on the rocket, resulting i...

AI Technical Summary

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
