Study on Energy Absorption Characteristics of Automobile Energy-absorbing Box with Honeycomb Sandwich Structure
The research object of this paper is the energy absorption box in low-speed collision traffic accidents.By studying the structural parameters of the car energy absorption box,a reasonable structure to improve its energy absorp-tion characteristics is found.The energy absorption box is filled with hexagonal,quadrilateral and honeycomb sandwich structures respectively.By combining theoretical analysis and numerical simulation,the energy absorption characteristics of traditional energy absorption box and honeycomb filling structure car energy absorption box are studied to improve the energy absorption characteristics of traditional energy absorption box.The research results show that:after filling,the energy absorption characteristics of the energy absorption box are greatly improved,and the honeycomb sandwich struc-ture of the energy absorption box also reduces the peak impact force of the traditional energy absorption box,which has important innovation,provides a new choice for the development of automotive energy absorption box,and provides an important reference for the safety design of vehicles.
