Background

The front end and the rear end of the vehicle are provided with bumpers which not only have the decoration function, but also are more important to be safety devices which absorb and buffer the external impact force and protect the vehicle body and passengers.

For many years, front and rear bumpers of vehicles are mainly made of metal materials, U-shaped channel steel is punched by steel plates with the thickness of more than 3 millimeters, chromium plating is carried out on the U-shaped channel steel, the U-shaped channel steel is riveted or welded with frame longitudinal beams, a large gap is formed between the U-shaped channel steel and a vehicle body, and the appearance of an attached part is quite unattractive.

With the development of the vehicle industry and the high volume use of engineering plastics in the vehicle industry, vehicle bumpers have also moved to the way of innovation as an important safety device. At present, the front and rear bumpers of the vehicle are required to be harmonious and unified with the shape of the vehicle body and to be light in weight in addition to the original protection function. The front and rear bumpers of a car are all made of plastic and are called plastic bumpers. Wherein the outer plate and the buffer material are made of plastics, and the cross beam is punched into a U-shaped groove by a cold-rolled sheet with the thickness of about 1.5 mm; the outer plate and the buffer material are attached to the cross beam, and the cross beam is connected with the frame longitudinal beam through screws and can be detached at any time. The plastic used for the plastic bumper is mainly made of polyester and polypropylene materials by an injection molding method.

Detailed Description

The self-adaptation is a process of automatically adjusting a processing method, a processing sequence, processing parameters, boundary conditions or constraint conditions according to data characteristics of processing data in the processing and analyzing processes so as to adapt to statistical distribution characteristics and structural characteristics of the processed data, thereby obtaining the optimal processing effect. The adaptive process is a process of continuously approaching an object, and the path followed by the adaptive process is represented by a mathematical model, which is called an adaptive algorithm. Gradient-based algorithms are commonly used, with the least mean square error algorithm, the LMS algorithm, being particularly common.

Adaptive control is a subject of research that has uncertain system control problems. It is a branch of the basic disciplines of "engineering theory of control". Adaptive control can be viewed as a feedback control system that intelligently adjusts its characteristics based on environmental changes so that the system can operate optimally according to some set criteria.
