摘要
以乘用车侧围门洞的结构特征为研究对象进行紧凑化设计研究,系统阐述了紧凑化设计的原则、方法和技术方案,通过结构拆解获得门洞结构的硬点和断面模型,以硬点驱动断面进行设计,并定义紧凑化系数和建立参数化设计表,兼顾电池布置的可行性及其对门洞设计的影响,以尽可能在有限的整车尺寸范围内实现人机空间最大化,改善上下车方便性,并综合考虑造型、碰撞安全、轻量化等多维度要素。最后,经分析验证确认了设计方法的有效性和可行性。
With the structural characteristics of the passenger car side wall door opening as the research object to conduct compact design research,this paper elaborated systematically the principle,method and technical solution of the compact design.The hard point and section model of the door opening structure were obtained through structural disassembly.The hard point driven section was used for design,and the compact coefficient was defined and a parametric design table was established.The feasibility of battery layout and its impact on the door opening design were considered,to maximize the manmachine space within the limited vehicle size range as far as possible,improve the convenience of getting on and off the vehicle,and comprehensively consider multi-dimensional elements such as modeling,collision safety,lightweight,etc.Finally,the validity and feasibility of the design method were verified by analysis.
