Abstract

The invention belongs to the crash test technology field and discloses an engineering mechanics crash test device. The device comprises a test bench and a slide rail arranged on an upper surface of the test bench. Left and right sides of the upper surface of the test bench are provided with a positioning hanging ring and a limiting baffle block. The slide rail is provided with a slide block. A right side wall of the slide block is fixedly connected to a collision head. A left side wall of the slide block is provided with a hook adaptively connected to the positioning hanging ring. An upper side of the right side wall of the slide block is connected to a stay cord. Through a cooperation effect of the positioning hanging ring and the hook, the slide block can be positioned and a self slide condition when the slide block is not used can be avoided. Through cooperation between a first magnetic plate and a second magnetic plate, a support effect on the slide block can be continuously maintained through a magnetic support mode. Through setting of an air outlet, an airflow can be output to support the slide block of an upper side so as to further support the slide block, and an influenceof friction on a test is reduced.

Description

technical field [0001] The invention relates to the technical field of crash tests, in particular to an engineering mechanics crash test device. Background technique [0002] Engineering Mechanics is a discipline that cultivates the basic theoretical knowledge of mechanics, calculation and experiment ability, and guarantees to be engaged in various engineering (such as machinery, civil engineering, materials, energy, transportation, aviation, ships, water conservancy, chemical industry, etc.) The relevant scientific research, technology development, engineering design and mechanics teaching work are going on smoothly. In order to analyze the structure test more accurately and vividly, it can be simulated by the test device. In engineering mechanics, crash test is the most basic and effective method to check structural performance, and is widely used in vehicle test engineering. [0003] For example, the Chinese Patent Publication No. CN208569944U discloses a crash test dev...
