The development of health monitoring technologies for aerospace systems creates a number of challenges for the community of engineers and technical specialists as they seek to integrate the technology into well defined working practices. These challenges do not just extend to the technical, but require a number of commercial questions to be addressed. It is of vital importance, that there is a clearly identified need for aerospace health monitoring, both from a technological and commercial viewpoint. If these needs cannot be identified, then any attempt for marketing health monitoring as a necessary future technological requirement is doomed for failure. Health monitoring technology will need to either deliver significant cost saving benefits to the aircraft operator or demonstrated increases in aircraft safety. The objective of the paper is to provide an assessment of the commercial benefits and development of aircraft landing gear health monitoring. The commercial need and challenges for health monitoring systems are explored in this paper within the context of a changing aerospace maintenance industry and the role in which new systems technology will play. The key findings of the research study are that within the aerospace industry there is a desired paradigm shift within aircraft maintenance towards offering maintenance systems with predictive capabilities. This maintenance revolution will not just incorporate new technologies, but will result in aircraft maintenance packages tailored towards individual customer requirements. The study illustrates the state-of-the-art in health monitoring currently restricts aerospace integration and a number of key technical and commercial issues need to be addressed. Predictive health monitoring offers a variety of commercial benefits for maintenance providers, aircraft operators and manufacturers. However, in order for these benefits to be realised increased transparency in maintenance related information is required between these key players. 相似文献

从汽车的概念设计阶段就把装配可行性考虑其中,并且一致持续到批产以后。首先,在概念设计阶段,用专家系统对设计进行验证;然后,在设计开发阶段,对设计进行装配评估,检查是否满足装配的基本要求;装配可行性分析,对设计进行静态检查,装配路径生成,工具空间检查,和人机工程验证;紧固件检查,检查紧固件是否和标准一致,以降低紧固件的种类和数量;接着开始整车虚拟装配模拟,以发现设计中的错误,及时改进。最后生成装配工艺文件和特殊工装的设计要求。这样的面向设计的计算机辅助装配工艺规划系统,缩短了开发时间,降低了开发的成本,提高了开发的效率。 相似文献
