摘要
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
A new method based on SFEM (Stochastic Finite Element Method) is developed for the calcualtion of reliability of structures. The corresponding computation formulas have been deduced when the nodal loads are stochastic and the plate and shell element are taken into consideration. Finally, the reliability of the telescopic jib of the QTJS160 Railway Crane has been calculated.
