【 摘 要 】

Due to the heterogeneity in raw materials and randomness in manufacturing processes, rubber products, even in the same batch, exhibit a certain fluctuation in their quality characteristics, such as physical size. Such a fluctuation will lead to a reliability fluctuation in their working conditions when putting them into use. Confronted with this problem, this paper develops a new reliability model for the performance degradation of rubber products with quality fluctuation. Furthermore, this paper proposes a quality requirement design method for rubber products based on the reliability constraint to further specify the quality requirement in the manufacturing process and effectively improve the reliability of rubber products. The effectiveness of the proposed reliability model and the quality requirement design method is illustrated using a real case study of rubber sealing O-rings.
