Test method for testing reliability of rocket high-temperature environment steel plate riveting process

Abstract

The invention provides a test method for testing the reliability of a rocket high-temperature environment steel plate riveting process. The test method comprises the following steps of determining thenumber of test pieces; manufacturing a corresponding number of test pieces according to a rocket steel plate riveting process structure; testing all the test pieces sequentially; preheating the testpiece in a thermal environment, applying a force load to the test piece after the test temperature is reached, keeping the test temperature unchanged, and detecting the deformation of the test piece for the first time; removing the force load, and detecting the deformation of the test piece for the second time; removing the thermal environment, and detecting the deformation of the test piece for the third time; and judging whether the steel plate riveting process is reliable or not. The test method provided by the invention conforms to the national general standard, the test load simulates thereal situation of the rocket high-temperature environment, the blank of the method for verifying the reliability of the steel plate riveting process in the high-temperature environment is filled, theverification problem of the new technology before application is solved, and sufficient support can be provided for the production of the steel plate riveting process in the high-temperature environment.

Description

technical field [0001] The present disclosure generally relates to the field of aerospace manufacturing, and specifically relates to a test method for testing the reliability of a steel plate jointing process in a high-temperature environment of a rocket. Background technique [0002] At present, my country's aerospace industry is developing rapidly, and new processes and technologies are constantly emerging in the field of aerospace manufacturing. Due to the gradual improvement of the technical indicators of the rocket's flight speed and mission load, the rocket structure must not only be resistant to high temperatures but also have sufficient strength, and the high-temperature-resistant steel plate riveting process has emerged. [0003] For the new technology, that is, the riveting process of the steel plate in the high-temperature environment of the rocket, the steel plate material must meet the two indicators of high temperature and strength at the same time, and the riv...

Problems solved by technology

[0004] It is precisely because the riveting process of the steel plate in the high-temperature environment of the rocket is the first in China, the current traditional method of simply testing the mechanical structure or thermal performance cannot meet the reliability inspection requirements of the steel plate in the high-temperature environment of the rocket. and operation have brought great hidden dangers
