Problems solved by technology

According to relevant research, the thickness of Chinese rib bone density is significantly smaller than that of Americans, which shows that the chest of Chinese people is more likely to be injured than Americans in the same collision, and the performance of the ribs of the dummy directly affects the strength of the chest during the collision. Safety protection performance, but at present, there is no rib material and preparation process for Chinese crash test dummies

Abstract

The invention discloses a preparation method of a dummy rib material suitable for a collision test of Chinese people, which comprises the following steps: weighing raw materials according to a formula, adding a heat stabilizer into dioctyl phthalate, and uniformly stirring; then sequentially adding second polyvinyl chloride resin, first polyvinyl chloride resin, stearic acid, calcium stearate, ethylene-vinyl acetate copolymer, powdered nitrile rubber, antimony powder and part of graphite powder, and mixing to obtain a mixture; wherein after each raw material is added, the next raw material is added after the raw materials are uniformly mixed; the obtained mixture is plastified, the remaining graphite powder is added multiple times after plastifying, after uniform plastifying, the material is added into a preheated mold, heat preservation, hot pressing, pressure relief and cooling are conducted, and the dummy rib material suitable for the collision test of the Chinese is prepared. And repeated use can be realized.

Description

technical field [0001] The invention relates to the technical field of safety of manned vehicles, in particular to a method for preparing a rib material of a crash test dummy suitable for Chinese people. Background technique [0002] As a key technology to measure manned vehicles, test dummies directly affect the safety design of manned vehicles, which have the effect of "technical weight". , which is made according to the main size and biological characteristics of adult males in Europe and America. However, there are differences between Chinese human body characteristics and European and American human characteristics, which will be reflected in the material properties of crash test dummies. According to relevant research, the thickness of Chinese rib bone density is significantly smaller than that of Americans, which shows that the chest of Chinese people is more likely to be injured than Americans in the same collision, and the performance of the ribs of the dummy direct...
