Evaluation methods of vehicle lightweight
摘要
Abstract
The level of vehicle lightweight was not able to accurate evaluated currently, which is closely related to fuel consumption. Three kinds of evaluation methods of lightweight were obtained by analyzing typical vehicles’data in this paper:For congener vehicle,taking 4-door sedan and sport utility vehicle as examples,vehicle areal density(L0=Wk/A,Wk is curb weight,A is area of tread width times wheelbase)increases approximate linearly with increasing A. To quantitative representation , vehicle relative areal density (ΔLm) was deduced;lightweight levels were divided to 7 grades;for different type vehicle,considering probability of passengers’number,methods of per capita lightweight coefficient was proposed;relative lightweight coefficient was presented , which has been validated by evaluation of front crossbeam assembly.关键词
