High-overload loading apparatus based on structural vibration under stress wave transmission loading

Abstract

The invention discloses a high-overload loading apparatus based on structural vibration under stress wave transmission loading. The apparatus comprises a pedestal with a hollow upper part, the top ofthe pedestal is fixedly connected with a vibrating body through first fixed connection structures, the bottom of the vibrating body is fixedly connected with a device to be detected through second fixed connection structures, and a loading source is arranged outside the vibrating body. The loading intensity of the loading source is changed to adjust the intensity of incident stress waves and change the intensity of transmission stress waves entering the device to be detected, so the overload level of the device to be detected is adjusted.

Description

technical field [0001] The invention relates to a high overload loading device, in particular to a high overload loading device based on structural vibration under stress wave transmission loading. Background technique [0002] With the widespread application of penetrating weapons such as ground penetrating bombs, higher requirements have been placed on the anti-overload performance of key components such as fuzes, pyrotechnics, and charges inside the missile body. If the above-mentioned components are deformed during the penetration process , damage to lead to functional failure, may lead to failure of the entire weapon system. Therefore, the anti-overload performance of key components is the key to determine the success or failure of the weapon system. [0003] At present, commonly used high-overload loading technologies include field test technologies such as 82mm artillery, 85mm artillery, 156mm artillery, balance guns, and rocket skids. These test technologies have co...
