Carbon fibre reinforced plastic for smartness car body design, practice and simulation

Abstract

With the vigorous implementation of national policies and regulations such as energy-saving and emission reduction, lightweighting has become one of the trends in the development of the automotive industry, which is of great significance in reducing energy consumption and increasing the range of vehicles. This paper is based on a newly developed smartness car body designed for elderly users, which aims to solve the problem of mobility and companionship for the elderly, with a maximum speed of 20 km/h and a weight requirement of 45 kg or less. This paper focuses on the lightweight technology of the body of the smartness car, using carbon fibre composite material as the carrier, and using simulation analysis combined with experimental testing to systematically study the body material selection, structure and process, and to carry out force analysis, finite element analysis and modal analysis on the designed body, verifying that the body of the smartness car meets the lightweight design requirements.
