摘要
针对高精尖产品尤其是航天类大型复合材料结构件质量风险识别的问题,通过对生产流程的分析,优化了失效模式识别的原理和流程;结合复合材料结构件的成型流程和生产要素提出了失效模式的识别方法。通过增加评价维度提高严重度(S)、可探度(D)评价准则的有效性;采用相似工序法对频度(O)进行准确定义。并结合CZ-5整流罩的生产流程阐述了PFMEA在大型航天复合材料结构件成型中的应用,为小批量多品种产品规避质量风险提供借鉴。
Aiming at the problem of quality risk identification of high-precision products, especially aerospace composite structural parts, the failure mode identification method is proposed by analyzing the production process and combining the molding process and production factors of composite structural parts. The effectiveness of the severity (S) and detectability (D) evaluation criteria is improved by increasing the evaluation dimension, the frequency (O) is accurately defined by the similar process method. Combined with the production process of CZ-5 fairing, the application of PFMEA in the forming of large-scale aerospace composite structural parts is expounded, which provides a reference for small batches of multi-variety products to avoid quality risks.
