Problems solved by technology

In addition, the size of the sample used in the experiment is small, and the impact force of the experimental device is low, so it is impossible to evaluate the ability of the plate to resist the impact of high-speed blocks on a macro level
[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention relates to the technical field of material impact resistance testing, and provides a vehicle plate impact resistance testing device, comprising a base body; one end of the base body is provided with a launching component, and the other end is provided with a fixing plate; The launch cylinder; the cylinder of the launch cylinder is filled with a powder pack, and the cylinder mouth is placed with an impact ball; a reversing tube is arranged just above the cylinder opening of the launch cylinder; Thereby, the present invention makes the impact ball obtain a higher initial velocity through the impact force generated by the explosion of the powder package in the launch cylinder, and impacts the plate to be tested. Through multiple sets of input parameters and test results, the impact resistance of the sheet is qualitatively and quantitatively evaluated; it provides an accurate and rich data basis for formulating the impact resistance test standard of the vehicle sheet. The invention has the advantages of simple structure, convenient operation, many parameter changes, and accurate and comprehensive test results.

Description

technical field [0001] The invention belongs to the technical field of material impact resistance testing, and in particular relates to a vehicle plate impact resistance testing device. Background technique [0002] The anti-collision ability of the vehicle is one of the key indicators to evaluate the safety performance of the vehicle. The body made of the vehicle sheet is the main structure to resist the collision. [0003] Vehicles are complicated when they are hit. The core purpose of the currently commonly used vehicle crash test is to test the overall deformation and damage of the vehicle under high-speed impact. However, the vehicle crash test cannot test the impact resistance of the body panels, especially the ability to resist the impact of high-speed small-sized block materials. [0004] The existing impact toughness test is used to evaluate whether the microstructure of the material meets the standard. In addition, the sample size used in the experiment is small...
