Problems solved by technology

[0002] According to previous project development experience and lessons, the bulkhead instrument bracket has the problem of severe vibration environment amplification (magnification of more than 10 times). Since this problem is generally found in the system-level test in the development stage, or even ignored, it is effective for the ground test of the instrument. Performance, product environmental adaptability, etc. are all harmful, burying serious hidden dangers for project development progress and flight reliability
In related technologies, the traditional "posteriori" vibration environment control method is usually used, which is highly dependent on ground vibration tests

Abstract

Embodiments of the present application provide a dynamic characteristic analysis method, system, terminal and medium of an instrument support, which relate to launch vehicle technology. The method includes: using finite element simulation to analyze the vibration characteristics of the instrument support to be analyzed, obtaining an analysis result, and determining a magnification of the instrument support according to the analysis result; when the magnification does not meet the corresponding requirements, triggering Perform structural adjustment on the instrument support until the magnification meets the corresponding requirements.

Description

technical field [0001] The present application relates to launch vehicle technology, and in particular, to a dynamic characteristic analysis method, system, terminal and medium of an instrument support. Background technique [0002] According to the development experience and lessons of previous projects, the bulkhead instrument support has the problem of serious vibration environment amplification (amplification of more than 10 times). Since this problem is generally found in the system-level test in the development stage, or even ignored, it is effective for the instrument ground test. The performance and environmental adaptability of the product are all relatively harmful, which will lay a serious hidden danger to the project development progress and flight reliability. In the related art, the traditional "a posteriori" vibration environment control method is usually used, which is highly dependent on the ground vibration test. SUMMARY OF THE INVENTION [0003] Embodim...
