摘　　要：针对FSAE赛车车身结构设计中碳纤维单体壳车身制造工艺复杂、成本高以及传统钢管桁架式车身扭转刚度较低的问题,提出了一种基于蜂窝铝板的新型单体壳车身结构,以实现高扭转刚度和低制造成本的目标。确定了车身扭转刚度和总质量的设计目标,并通过人机工程设计确定了车身的基本尺寸;采用有限元分析方法得出了最优的铺层方案,并对车身在各工况下进行了强度校核分析。研究结果表明,铝合金半单体壳车身具有良好的扭转刚度和轻量化水平,是一种性价比优良的新型车身结构,可替代传统的钢管桁架式车身。本研究为FSAE赛车提供了新的车身设计思路。An innovative monocoque chassis design for FSAE racing cars utilizing honeycomb aluminum panels is proposed to address the challenges associated with the complex manufacturing process and high cost of carbon fiber monocoque chassis,as well as the low torsional rigidity commonly found in traditional steel tube spaceframe chassis design.The design objectives for torsional stiffness and total mass of the chassis are determined,and the basic size of the chassis is established through ergonomic design principles.The optimal layup scheme is obtained using the finite element analysis method,and the chassis undergoes strength verification analysis under various working conditions.The results demonstrate that the aluminum semi-monocoque chassis exhibits excellent torsional rigidity and lightweight characteristics,making it a cost-effective alternative to the traditional steel tube spaceframe body.This research provides a fresh perspective on chassis design for FSAE racing cars.
