The biggest problem with new energy vehicles currently is their short range.Lightweight design can some extent increase range and duration,and for traditional fuel vehicles,it can also reduce emissions and fuel consumption.This article takes a certain model of 18 m articulated electric bus as an example,and uses finite element software to optimize the size of the entire vehicle skeleton for lightweight design.In the end,the electric articulated bus lost 0.6 t of weight compared to the original skeleton,with a weight reduction rate of 13.1%,and the effect is significant.In summary,the lightweight scheme proposed and verified in this article is reasonable and effective,and has practical significance for improving the power performance and increasing range of new energy electric vehicles.
