Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobiles, and particularly relates to a modularized tool for testing explosion-proof materials. BACKGROUND

[0002] In order to verify the explosion-proof performance of bulletproof vehicles, cash transport vehicles, armored vehicles and other special vehicles, the explosion-proof performance test of the special vehicles is needed before the mass production of the vehicles. Since the special vehicles are expensive, the explosion-proof special performance of the steel plates and other materials of the vehicles needs to be fully verified before the vehicles are prepared. In order to make the material test as close as possible to the actual vehicle application scene and the special test conditions of the whole vehicle, the preparation and processing of the materials need to be as close as possible to the actual application parts and assemblies of the vehicles, and the test conditions should also be the same as the special performance test conditions of the whole vehicle.

[0003] At present, the material explosion-proof test mainly simulates the actual explosion-proof situation of the vehicle. The tool is mainly a simple steel frame. The steel plate is fixed on the steel frame through screwing. The grenade is placed below the steel plate or below for explosion-proof special performance test. However, such tool has the following problems:

[0004] 1. The overall quality of the steel frame plus the steel plate is lighter than the actual vehicle. When the explosion occurs, the steel plate flies, so that the impact kinetic energy is converted into potential energy, reducing the impact work received by the material, which may cause the material test to be problem-free while the whole vehicle test fails;

[0005] 2. If the steel frame is too heavy, the overall quality of the steel frame plus the steel plate is too heavy, part of the impact kinetic energy cannot be converted into potential energy, increasing the impact work received by the material, which may cause problems in the material test, and then increase the thickness of the material, so that the quality of the whole vehicle is increased without meaning, which cannot achieve the purpose of lightweight of the whole vehicle. However, if the steel plate + steel frame quality is designed according to the actual whole vehicle quality every time, it cannot meet the test cycle and test cost control purposes of various vehicle models of the vehicle enterprise;

[0006] 3. At present, the connection mode of the steel frame is ordinary bolt. When the connection is impacted by the fragment, the connection is easy to deform and crack, so that new bolts need to be installed, which prolongs the test time and also causes waste. SUMMARY

[0007] In view of the above defects in the prior art, the present application provides a modularized tool for testing explosion-proof materials, which can meet the explosion-proof test of various quality vehicle models using the same tool and bolts, and can complete the material test of multiple parts at one time according to the demand, greatly reducing the test cost and test cycle.
