运用静态和动态的有限元分析对采用CBF技术(部件内置到车架)的KAZ-Ⅱ电动车新车架结构的设计和研究过程进行仿真。结果表明,与KAZ的车架结构相比较,这种车架的弯曲强度提高了402%,抗扭强度提高了104%;这种结构能够避免驾驶室受到挤压,进而避免驾驶室变形,让乘员免受伤害。研究结果提供了设计电动汽车刚性和安全车身结构的一种方法,并展示了电动汽车在未来汽车系统中的优势。
The static and dynamic finite element analysis was used to simulate the design and research process of the new frame structure of KAZ-Ⅱ electric vehicle adopting CBF technology (components are built into the frame). The results show a 402% increase in flexural strength and a 104% increase in torsional strength compared to the KAZ frame structure; this structure avoids crushing of the cab and thus avoids deformation of the cab to Occupant from harm. The findings provide a way to design a rigid and safe body structure for electric vehicles and show the advantages of electric vehicles in future automotive systems.
