STRUCTURE OF VEHICLE BUMPERS AND THEIR DURABILITY TESTS

Abstract

Car bumper is a part that absorbs and reduces external impact and protects the front and rear ends of the car. Many years ago, the front and rear bumpers of cars were stamped with steel plates to the channel steel, riveted or welded to the longitudinal beams of the frame and had a large gap with the body, they looked very ugly. With the development of the automotive industry and the widespread use of engineering plastics in the automotive industry, the car bumper is also on the way to innovation as an important tool for car safety. The front and rear bumpers of today's cars not only retain the original protective function, but also strive for harmony and unity with the body shape and strive for their light weight. Front and rear bumpers of cars are made of plastic. People call them plastic bumpers.
