研究了类菱形概念车的特殊布置方式。根据中国新车评价规程(C—NCAP)侧碰试验的要求,在同一建模方法下建立了类菱形概念车与某常规轿车的侧面碰撞有限元模型,并对二者的侧向刚度及侧碰性能进行了分析与对比,结果表明类菱形概念车侧向刚度及侧碰性能均明显优于常规轿车。
The particular layout of a rhombus concept car had been studied. According to the requirements for the side impact test of C--NCAP(China new car assessment program) ,the side impact finite element models of the rhombus concept car and a conventional car were built with the same modeling method. The comparisons between the simulation results of the two models indicate that lateral stiffness and crashworthiness of the rhombus car is much better than the latter.
