摘要
建立了起重机回转支承装置的极限状态方程,确定了滚动体应力和强度的分布类型及分布参数,利用应力强度干涉理论,建立了回转支承可靠度计算的模型和算法,并给出了计算实例。
A limit state equation of slewing bearing of cranes is built,and distributing type and distributing parameters of stress and strength for roller are calculated Based on theory of stress interference with strength,an algorithm and a model of reliability calculation for slewing bearing are established,and an example of calculating is given.
