Energy absorption structure of hazardous chemicals transport vehicle

Abstract

The invention provides an energy absorption structure of a hazardous chemical transport vehicle, comprising a cylindrical energy absorbing tube and a pyramidal pressure resistant cap, wherein the pressure resistant cap is of a hollow structure, a protective layer is arranged on each surface of the pressure resistant cap, the end face of one end with large outer diameter of the pressure resistant cap is a plane; the outer surface of the energy absorbing tube is a conical surface; and one end with small diameter of the pressure resistant cap is inserted into the thin wall end of the energy absorbing tube. The energy absorbing tube is made by adopting aluminium magnesium alloy, and the pressure resistant cap is made by adopting Q235 or Q236 steel. A tearing opening is formed in the thin wall end of the energy absorbing tube along the axial direction of the energy absorbing tube. A friction guide ring is arranged on the inner wall of the thin wall end of the energy absorbing tube. The energy absorption structure is simple and easy to process, design of the taper grade of the pressure resistant cap is reasonable, and with the taper grade, force application to the energy absorbing tube is optimal in collusion, so that the washboarding of the energy absorbing tube is performed according to preset manner, and therefore, energy produced in collusion can be sufficiently absorbed, harm caused by collusion impact is reduced, and safe of the vehicle is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of vehicle anti-collision equipment, and in particular relates to an energy-absorbing structure of a vehicle transporting hazardous chemicals. Background technique [0002] At present, the birth of automobiles has brought various conveniences to human life. At the same time, traffic accidents have increased continuously. Car accidents have also brought many shadows to human beings. Drivers and passengers desire more protection for people and vehicles when traveling. When a vehicle hits an obstacle ahead at a relatively high speed, the vehicle will receive a large impulse, resulting in a large obstacle acceleration that makes the vehicle drop from high speed to a standstill in an instant, and the original large kinetic energy is almost completely converted into the internal energy of the vehicle, making The vehicle was severely damaged and deformed, resulting in casualties of people in the cockpit. Therefore...
