摘要： 为实现碳纤维增强复合材料（carbon fiber reinforced polymer，CFRP）油底壳的替代与制造，结合复合材料铺层可制造性分析软件FiberSim与铺层结构优化模块Optistruct，对CFRP油底壳开展了结构与制造工艺并行优化设计。参照CFRP壳体类零件的成型过程，采用FiberSim软件制定了满足制造工艺要求的CFRP油底壳铺覆方案。并在此基础上，分别以CFRP油底壳刚度最大、质量最小为优化目标，以振动模态、制造工艺要求为约束，采用Optistruct模块对CFRP油底壳的铺层结构进行优化设计。经仿真分析验证，制造工艺调整后的CFRP油底壳满足各项替代要求，且CFRP油底壳的质量较原金属油底壳减小了56.7%。所提出的结构与制造工艺并行优化设计方法可较好地兼顾结构特征、复合材料设计及制造工艺要求，为复合材料产品的优化设计提供了参考。
Abstract: In order to realize the replacement and manufacture of carbon fiber reinforced polymer （CFRP） oil pan, the concurred optimal design of structure and manufacturing process of CFRP oil pan was carried out by combining the composite material layer manufacturability analysis software FiberSim and the layer structure optimization module Optistruct. With reference to the forming process of CFRP shell components, a CFRP oil pan covering plan that met the manufacturing process requirements was developed by the FiberSim software. Based on this, taking the maximum rigidity and minimum mass of CFRP oil pan as the optimization goals, and the vibration mode and manufacturing process requirements as constraints, the layer structure of CFRP oil pan was optimized by using the Optistruct module. The simulation analysis showed that the CFRP oil pan after the adjustment of manufacturing process met various substitution requirements, and the mass of the CFRP oil pan was reduced by 56.7% compared with the original metal oil pan. The proposed concurred optimal design method of structure and manufacturing process can take into account the structure characteristics, composite material design and manufacturing process requirements, which provides a reference for the optimal design of composite material products.
