Survey of optimization methods for BIW lightweight design

Abstract

Abstract. The body lightweight is important to the vehicle design and development, which has become one of the main research subjects in vehicle industries and research institutes. This paper systematically expounds the background and significance of the lightweight design of automobile, and systematically expatiates the implementation method of the light weight of the vehicle from the fields of lightweight materials, body structural optimization design, molding technology and new connecting technologies. The present situation of domestic and foreign research on lightweight design is introduced at the same time. On this basis, this paper establishes the process of multidisciplinary lightweight design of vehicles, and applies a variety of simulation and modeling tools into this process. The experiment results show the effectiveness and efficiency of the method

A Review on Advance Materials and Techniques Used in Automobile Application

“…Compared with the previous aluminum stent, plastic stent has a better acoustic properties and thermal insulation performance, as well as lighter quality and better carrying capacity. Because they are lightweight, many non-metal parts, such as plastic and fibre glass, are used in the automotive, aerospace and marine industries [2].…”

“…While designing the vehicle, the following requirements must be meet vibration, noise and ride comfort (Noise Vibration Harshness); stiffness, strength and crashworthiness requirements of the entire vehicle; reliability, etc. Therefore, many scholars have applied the research methods of multi-objective algorithms to the design of automotive lightweight [2].…”

“…The board surface with TRB technology is smooth and beautiful, and can be widely used in automobile body outer panel. Ford Focus B pillar was produced by TRB technology [2].…”

“…It can realize the strength design of parts, prolong the life of parts and simplify the production process. TRT technology can be used in the production of A, B pillar, sub frame and other components [2].…”

“…Lightweight vehicle body can easily be produced by developing new body constructions with the use of lightweight materials and implementation of structural optimizations. New body construction uses High Strength Steel, Aluminium, Magnesium and Carbon Fiber Reinforced Plastic as lightweight materials for the reduction of overall weight of an automotive body [1][2][3].…”
