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 shock resistance testing, and provides a vehicle plate shock resistance testing device which comprises a base body. One end of the base body is provided with a transmitting assembly, and the other end is provided with a fixing plate; the launching assembly comprises a vertically-arranged launching cylinder. A gunpowder bag is contained in the launch canister, and an impact ball is placed at the opening of the launch canister; a reversing pipe is arranged over a cylinder opening of the launching cylinder. A speed measuring assembly is arranged at the position of a horizontally-arranged pipe opening of the reversing pipe. Therefore, the impact force generated by explosion of the gunpowder bag in the launching cylinder enables the impact ball to obtain a relatively high initial speed to impact a to-be-tested plate. The impact resistance of the plate is evaluated qualitatively and quantitatively through a plurality of groups of input parameters and test results; and an accurate and abundant data basis is provided for formulating an impact resistance test standard of the vehicle plate. The device is simple in structure, convenient to operate, multiple in parameter change and accurate and comprehensive in test result.

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 a vehicle is one of the key indicators for evaluating the safety performance of a vehicle. The body made of vehicle plates is the main structure to resist 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 size of the sample used in the experiment is small,...
