Description
Summary:With advancements in aerospace technology, the development goal of future mechanical aerospace products is to create low-cost, high-reliability, and generalized products to satisfy the requirements of different mission profiles. However, traditional development tests for mechanical products are typically not implemented under environmental conditions or operational stress beyond the design limit. Hence, they cannot obtain the design and working limits of the product. Consequently, providing quantitative support for the adaptability of the developed product is difficult. With the increased development needs of mechanical aerospace products, sensitive stresses affecting product quality have been identified in this paper by analyzing historical quality problems of similar products and promoting FMEA analysis. The analysis of sensitive stress via a reliability enhancement test for mechanical aerospace products has been proposed to fully stimulate weakness of mechanics and improve the inherent reliability of products through design improvements.
