摘要
基于垫片时效泄漏模型和应力强度干涉模型建立螺栓法兰连接的模糊可靠性模型。通过对极限状态方程进行模糊化处理,得到了螺栓法兰连接模糊可靠性计算模型,将Monte-Carlo法和有限元法相结合,提出基于有限元的螺栓法兰连接模糊可靠性计算方法,并对该方法进行验证。
Basing on time-correlated leakage model and stress-strength interference model,the fuzzy reliability model for bolted flange connections was established ; and through fuzzy processing of the limit state equation,a model for calculating the fuzzy reliability was obtained,including a calculation method based on Monte-Carlo and finite element method and its verification through examples.
