结合板壳元 ,在载荷随机的情况下 ,给出了利用随机有限元计算大型、复杂结构可靠度的方法 ,推导了相应的计算公式 ,计算了 QTJS1 60铁路起生机伸缩式吊臂的可靠度
Combined with the shell element, the method of using random finite element method to calculate the reliability of large and complex structures is given under the condition of random loading. The corresponding formulas are derived and the reliability of the telescopic boom of QTJS160 railway is calculated
