摘　　要：以汽车油底壳为研究对象,通过综合对比不同材料的屈服强度及工作环境,选定轻量化目标材料为添加30%玻璃纤维的聚酰胺(PP66+30%GF)。通过等强度厚度设计,以弯曲刚度与弯曲强度为依据,分别计算轻量化目标材料厚度为1.3 mm和3.3 mm,在工作条件为1 650 Pa均布载荷条件下,使用ABAQUS软件分别对2种厚度的零件进行强度分析。结果表明,当零件厚度为3.3 mm时能满足工作要求,其设计过程为实际生产提供一定的参考依据和理论基础。Taking the automobile oil pan as a research object, the lightweight material was selected as a polyamide(PP66 + 30% GF) with 30% glass fiber added by comprehensively comparing the yield strength and working environment of different materials. Through the design of equal strength thickness, based on the bending stiffness and bending strength,the lightweight material thickness was calculated to be 1.3 mm and 3.3 mm, respectively.Under the 1 650 Pa uniformly distributed load conditions, the strength analysis of the two thickness parts was carried out by using the ABAQUS software. The results showed that when the part thickness was 3.3 mm, it could meet the work requirements, and it provided a certain reference and theoretical basis for actual production.
