本文以强度可靠度为约束,对法兰螺栓联接进行了优化设计.文中提出采用辛卜生数值积分较好地处理了正态分布数值表,从而将优化设计与可靠性设计有机地结合起来.在此基础上进行的法兰螺栓联接设计,可在满足一定强度可靠度的同时,迅速取得一组最佳结构参数,其设计方法具有广泛的实际应用价值. In this paper, the flange bolt connection is optimized by the strength reliability constraint. In this paper, we propose that the numerical value table of normal distribution can be handled well by using the integral number of SBS, so that the optimal design and the reliability design are organically combined Based on the flange bolt connection design, can meet a certain degree of reliability while quickly obtaining a set of the best structural parameters, the design method has a wide range of practical value.
