摘　　要：现阶段,汽车行业的发展十分迅速,汽车保有量也日益增加,随之而来的全球能源危机和环境污染也越来越严重,因此,汽车轻量化发展成为汽车产业可持续发展的必由之路。本文采用玻璃纤维增强聚丙烯(GFRPP)复合材料代替钣金作为风扇罩材料,根据某国产汽车风扇罩尺寸、主要装配关系以及使用要求,在不影响性能的前提下,确定全塑汽车风扇罩设计原则,完成汽车风扇罩设计。利用CATIA软件建立三维几何模型,并参考注塑制品的设计原则及成型工艺,通过Moldflow软件对成型过程进行工艺分析,研究相关参数的影响。最终完成的全塑风扇罩在满足整车设计要求的情况下可实现一体注塑成型,与传统钣金风扇罩相比减重42.5%。At this stage,the development of the automotive industry is very rapid,and the number of cars is increasing,and the ensuing global energy crisis and environmental pollution are becoming more and more serious.So the development of automobile lightweight has become the only way for the sustainable development of the automobile industry.In this paper,glass fiber reinforced polypropylene(GFRPP) composite material is used instead of sheet metal as the fan cover material.According to the size,main assembly relationship,and requirements of a domestic automobile fan cover,the design principle of all-plastic automobile fan cover is determined without affecting performance,and the design of automotive fan cover is completed.CATIA software is used to establish a three-dimensional geometric model.With reference to the design principles and molding process of injection molded products,the molding process is analyzed by Moldflow software to study the influence of relevant parameters.The resulting all-plastic fan cover can be molded integrally while meeting the design requirements of the whole vehicle,reducing the weight of the traditional sheet metal fan cover by 42.5%.
