Analysis of Anti-Riot Helmet Material Based on Numerical Simulation

摘要

Focusing on the problem that the modern anti-riot helmet has been revealed a number of deficiencies such as poor performance under impact, the material of helmet shell is analyzed based on numerical simulation in this paper. A finite element model of anti-riot helmet and simple finite element models of head, trunk and blunt object are established by CAD software and ABAQUS software. PP, PC and ABS are chosen as three different engineering plastics for anti-riot helmet shell material, and then carry a numerically simulation on the process of anti-riot helmet impact moment. Results show that the overall system kinetic energy curves present overall downward trends firstly, then present irregular waves with smaller ups and downs. PC is a more excellent helmet material while comparing to PP and ABS.
