Problems solved by technology

[0004] Due to the fast ejection speed, long ejection distance, and hard test site, if the traditional simulated load is used, the shell load will be broken and damaged due to the large impact force at the moment the load lands, and it cannot be reused many times, resulting in test failures. High cost, complex control and other issues

Abstract

The invention discloses a reusable ejection simulation load and a manufacturing method thereof. The ejection simulation load comprises a load main body, an elastic protection layer and a limiting structure, wherein the load main body comprises a solid body and a balancing weight, the balancing weight is arranged and fixed at a preset position on the solid body according to the requirement of simulating the mass center of the load, and the elastic protective layer is fixedly arranged on the outer surface of the load main body and is stably positioned on the load main body through the limiting structure; a plurality of micropore air gaps are formed in the elastic protection layer, and the elastic protection layer buffers impact force borne by the ejection simulation load during ejection through the micropore air gaps. The load has the advantages of being simple in load structure, high in engineering production realizability, capable of reducing development cost and the like, and effectively solves the problems that a traditional emission test simulation load is high in cost and cannot be integrated and reused.

Description

technical field [0001] The invention belongs to the technical field of ejection, in particular to a reusable ejection simulation load and a manufacturing method thereof. Background technique [0002] For the existing relatively mature ejection technologies, such as gas ejection, high-pressure nitrogen ejection, liquid-gas mixed energy ejection, electromagnetic ejection and other ejection methods, numerous repeated experimental verifications must be carried out before they are put into practical application, so that they can be compared and analyzed. The performance advantages of this ejection technology, and then choose the appropriate ejection method according to the actual engineering needs. For high-speed ejection technology, experimental verification is even more crucial. By repeating the experiment, collecting and organizing the experimental data, timely analyzing and solving the problems that arise during the experiment, to ensure the stability of the launch state. R...
