摘　　要：对碳纤维复合材料及结构优化设计方法进行了简单论述,重点应用结构优化方法,主要是尺寸优化和拓扑优化对碳纤维发动机罩进行了优化设计,并对原钢制发动机罩、优化前后的发动机罩进行了性能分析,验证了优化方案的可行性和优越性。First, carbon fiber composites and structural optimization methods are briefly discussed in this paper. Carbon fiber hood is optimized and designed mainly by structure optimization methods, which mainly include size optimization and topoh,gy optimization. The performance of the original steel hood, the hoods respectively before and after optimization are also analyzed. The feasibility and superiority of the optimization program are verified. Cnllaborative application of carbon fiber material and structural optimization technology in vehicle design is promoted in this paper, and has won expected research achievements.
