基于工艺过程的复合材料舱门制造成本评估

摘要

介绍了基于制造工艺过程的成本评估模型的基本特点，基于此模型开发了飞机制造成本评估软件，并对复合材料、金属和装配工时进行了估算，与相关文献数据吻合良好。应用该软件对复合材料舱门制造成本进行评估，并与金属舱门进行了比较，同时研究了生产批量及工艺方法等因素对复合材料舱门制造成本的影响。%The primary objective of this paper is to develop the cost estimation software for composite fabrication based on the existing cost models. On the basis of the manufacturing process-based cost modeling, a cost estimation code is developed. The simulations of compos-ite, metal and assemblage man-haur agree well with data in the correlative literature. The costs of two kinds of port manufactured with advanced composite and traditional metal materials are estimated. Finally the inlfuences of pro-duction batch and manufacturing method on the composite port fabrication cost are studied.
