以某款乘用车后排座椅骨架为例,采用长纤维复合材料(LFT)替换金属,在其初始结构无法满足GB15083-2006法规要求的前提下,采用拓扑优化方法分析座椅骨架的重点设计区域和传力路径,提出采用长纤维复合材料的座椅骨架新结构,并利用CAE仿真技术进行了验证.结果表明,新结构不仅能很好地满足法规要求,且质量相对金属结构减轻了约10%,轻量化效果明显.
以某款乘用車後排座椅骨架為例,採用長纖維複閤材料(LFT)替換金屬,在其初始結構無法滿足GB15083-2006法規要求的前提下,採用拓撲優化方法分析座椅骨架的重點設計區域和傳力路徑,提齣採用長纖維複閤材料的座椅骨架新結構,併利用CAE倣真技術進行瞭驗證.結果錶明,新結構不僅能很好地滿足法規要求,且質量相對金屬結構減輕瞭約10%,輕量化效果明顯.

Taking a car rear seat frame as example, which uses long fiber thermoplastic composites (LFT) to replace metal materials, topology optimization method is used to analyze the key design area of seat frame and the force transferring path, since the initial LFT structure can't satisfy the requirement of GB15083-2006. Then, a new seat frame structure with long fiber thermoplastic is presented and validated by CAE simulation technique. The results show that: the optimized structures can not only meet the requirements, but also have obvious lightweight effect with about 10% of the initial mass are reduced.
