Build a Safer, Effective Crash Box for Cars, Helicopters
A Crash Box with High Energy-Absorption Capacity Induced by Material Enhancement
Tags: City University of Hong Kong, Hong Kong, Transportation & Automotive
This invention presents a novel crash box designed for mid to high-level mass-produced passenger cars, enhancing vehicle safety by optimizing energy absorption during low-speed crashes. It features a polygonal cross-section that buckles upon impact, efficiently converting kinetic energy to reduce damage and protect passengers. This lightweight, high-strength component not only improves passive safety but also contributes to the automotive industry's goal of reducing greenhouse gas emissions. Its potential extends beyond cars to helicopters and highway guardrails, promising a significant market opportunity. The technology promises higher energy absorption, reduced weight, and lower initial peak force.
