Problems solved by technology

However, using this "momentum trapping" principle for soft recovery is a pure soft recovery technology, which can only achieve soft recovery of samples under low-speed (1km / s) loading, but is helpless for soft recovery of samples loaded at high speeds.

Abstract

The invention provides a recovery device for shock wave loading experimental samples, and relates to the field of shock dynamics. The recovery device for shock wave loading experimental samples comprises a recovery capsule, a cover and a cushioning material layer, wherein one end of the recovery capsule is a sample fixing end, and the other end of the recovery capsule is a recovery end; the cover is detachably connected with the recovery end and is used for closing the recovery end, and the cushioning material layer fits to the cover, and comprises a plurality of cushioning layers which are arranged side by side in a fitting way; the wave impedances of the cushioning layers increase in the direction from the sample fixing end to the recovery end. The invention also provides a soft recovery method. The recovery device and the soft recovery method provided by the invention have the advantages that the collision speed range of softly recovered sample targets can be widened, the secondary damage to the samples is avoided, and the soft recovery effect is good; when the high-speed sample targets are recovered, the required cushioning material layer is small in volume and light in weight, and is convenient to install and implement.

Description

technical field [0001] The invention relates to the field of shock dynamics, in particular to a recovery device and a soft recovery method for shock wave-loaded experimental samples. Background technique [0002] Impact dynamics is a branch of mechanics based on mechanics, materials science, and physics. The main research object is the dynamic behavior and structural characteristics of materials under impact loads, including the movement and deformation of material components under dynamic loads. , damage and failure. The main application fields are: blasting engineering, drilling and mining, mechanical processing, underwater explosive cutting, etc. [0003] The research on the impact dynamic characteristics of materials is an important basis for material design, structural performance and equipment safety assessment, and has a wide range of engineering demand backgrounds and important scientific value. The shock dynamics experiment under the condition of one-dimensional s...
