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

The embodiment of the invention provides an instrument support dynamic characteristic analysis method and system, a terminal and a medium, which relate to the carrier rocket technology. The method comprises the following steps of analyzing the vibration characteristics of an instrument support to be analyzed by adopting finite element simulation to obtain an analysis result, and determining the magnification times of the instrument support according to the analysis result, and when the magnification times do not meet the corresponding requirements, triggering the structure adjustment of the instrument support until the magnification times meet the corresponding requirements.

Description

technical field [0001] The present application relates to launch vehicle technology, in particular to a dynamic characteristic analysis method, system, terminal and medium of an instrument support. Background technique [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 relatively 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 relies heavily on ground vibration tests. Contents of the invention [0003] Embodiments of the present applicatio...
