A function-oriented quality control method for ship construction
-
摘要: 长期以来,由于舰船建造工程浩大、过程复杂、工艺繁多,人们对于建造质量如何影响舰船可靠性缺乏系统性的研究。为实现对考虑建造质量影响的舰船可靠性的科学预测和有效控制,从舰船总体功能的角度出发,在现代造船模式背景下,针对舰船建造提出一种以功能为导向的质量控制(FOQC)方法。融合舰船目标功能、质量参数、建造工艺因素,提出舰船建造可靠性预测模型。建立工艺—质量参数及质量参数—特征功能可靠性模型,对预测模型进行量化计算,获得建造质量对舰船可靠性影响的定性与定量分析,并依据分析结果,对关键质量点与关键工艺环节进行控制与优化。以某舰船轴系安装为实例进行分析,验证了方法的可行性与有效性,可为舰船建造质量的定量化检验与评价提供基础性方法的原理指导。Abstract: As ship construction is a large-scale, complex and problematic process, it lacks systematic research into how construction quality influences ship reliability. Aiming at the purpose of predicting and controlling ship reliability, this paper proposes a Function-Oriented Quality Control(FOQC) method to manage a ship's overall functions under modern ship-building conditions. Based on the system reliability theory, a reliability prediction model for ship construction composed of such factors as ship function, quality parameters and building process is proposed. We establish a quality-function reliability model and a process-quality model to both qualitatively and quantitatively calculate the impact of construction quality on ship reliability. According to the results, the control of key quality factors and processes can be implemented. The feasibility and effectiveness of the FOQC method are validated by a case involving the shafting installation of a ship.
