Embodiment Construction

[0008] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0009] Such as figure 1 As shown, the overall implementation mode of the spacecraft virtual vibration test system of the present invention is realized by building three major subsystems: (1) first set up the test database to provide operating data for the system function modules; (2) simultaneously establish the spacecraft virtual vibration test system The functional module uses the data in the database to realize the virtual vibration test function; (3) finally establishes the spacecraft virtual vibration test interface software system to realize the man-machine interactive parameter setting and module function execution.

[0010] The specific functional relationship and implementation method between each subsystem and its sub-modules are as follows:

[0011] (1) Test database

[0012] The data content of the test database includes the shaking ta...

Abstract

The invention relates to a virtual vibration test system for a spacecraft. The virtual vibration test system comprises a vibration test closed-loop simulation module for simulating a closed-loop control process of a real vibration test and executing closed-loop simulation calculation of a virtual vibration test, a model correction module for correcting a vibration table model, a fixture model and a spacecraft model, a test condition analysis module for indicating a downwards sunken magnitude and a downwards sunken frequency under a high-magnitude vibration test, a fixture evaluation analysis module for analyzing and evaluating the performance of a test fixture and performing modal analysis and virtual vibration test analysis on the fixture, and a test database for storing and supplying calling parameter data and file data to the functional modules. Due to the virtual vibration test, the conventional value simulation result is improved; an instructive measure is supplied to a real test design; insufficient-test and over-test are avoided; and the technical level of the test is enhanced.

Description

technical field [0001] The invention relates to a spacecraft virtual vibration test system, which is directly applied to the technical field of spacecraft vibration tests. Background technique [0002] With the changes in the international situation, the aerospace industry, as an important part of modern national defense, has received more and more attention. The level of aerospace also directly reflects the level of national defense in our country. With the vigorous development of the aerospace industry, the development of spacecraft has gradually realized the development from a single model to multiple models, and the scale of spacecraft has also become larger and larger. In order to meet the needs of current small batch production and meet the requirements of high reliability and long life of the model, it is necessary to shorten the development cycle, speed up the development progress and improve the development precision. At present, the development of spacecraft requi...
