在机翼方案设计阶段需要快速对复合材料机翼的制造成本进行评估.基于制造工艺成本模型开发了复合材料机翼成本估算模型.应用CATIA二次开发技术编制了模型生成器,实现了参数化建模过程自动化,并为成本模型提供计算所需几何特征信息.实现了机翼设计方案CAD模型与成本分析模型无缝连接的自动化计算过程,给出了实现该过程的流程和主要步骤.以某型无人机复合材料机翼为例,验证了该方法的确能对不同结构布置形式和不同外形的复合材料机翼设计方案进行快速成本评估.估算结果表明,在外形相同的情况下,梁的个数增加1个,肋的个数减少4个的复合材料机翼,其总成本增加了约2.5%;在结构布置相同的情况下,展弦比和梢根比的变化对该复合材料机翼总成本的影响不大.
