摘要
在分析影响螺栓联接可靠性不确定性因素的基础上,将不确定的载荷、应力等用凸模型中区间变量来描述,提出了螺栓联接静强度的非概率可靠性设计方法。该方法运算简便,对原始数据要求低。通过计算实例表明,该方法是合理和实用的。
Based on the analysis of uncertain factors affecting the connecting bolt reliability, internal model are used to describe the uncertain parameters such as load and stress. The non- probabilistic reliability design of the connecting bolt on static strength is proposed. The design method is a lower requirement for the initial data and simply computation. The proposed method is reasonable and efficiency by the example.
