Universal multi-connecting-rod type solid rocket engine vertical tool

Abstract

A universal multi-connecting-rod type solid rocket engine vertical tool comprises a front adapter plate (1), a rear adapter plate (8) and a base (9), the front adapter plate (1), the rear adapter plate (8) and the base (9) are correspondingly arranged from top to bottom, each of the front adapter plate (1) and the rear adapter plate (8) is of a circular ring structure, and the front adapter plate (1) and the rear adapter plate (8) are connected through a telescopic pull rod device in the circumferential direction, and the rear adapter plate (8) is connected with the base (9). The axial working state of an engine can be truly simulated, and the advantages of being adjustable in length size, adjustable in radial size, capable of being axially centered and the like are achieved; and the requirement of simulating the axial mechanical environment borne by the engine during work more truly can be met.

Description

technical field [0001] The invention relates to a vertical tooling for an engine, more specifically to a vertical tooling for a general multi-link solid rocket motor, and belongs to the technical field of vibration and impact tests. Background technique [0002] As the engine of rockets, missiles and sounding rockets, as well as the booster engine launched by spacecraft, solid rocket motors are subjected to various vibration and shock loads during the working process; therefore, solid rocket motors have high reliability and strong environmental adaptability Key to engine quality characteristics. Ground vibration and impact tests are the main ways to assess the environmental adaptability of solid rocket motors. They can not only test whether the performance of the engine meets the requirements, but also expose the design defects of this type of engine, thereby providing guidance for its optimization and improvement; During the impact test, in order to more realistically simu...

AI Technical Summary

Problems solved by technology

[0003] At present, there are more and more various types of aircraft using solid rocket motors, many of which require identification tests and batch sampling tests; while traditional vertical vibration shock tooling requires a large number of repeated processing tests according to different types of engines, resulting in processing Serious waste of materials, waste of test sites, and a lot of industrial waste

However, there is currently no general-purpose vertical tooling that can solve these problems. Therefore, it is urgent to design a more reasonable and efficient vertical vibration shock test tooling
