摘要
针对在用门机构件的疲劳开裂现象 ,提出了受压、弯、扭复合作用的构件可以等效应力作为裂纹萌生寿命的假定 ,并通过对某港口一台 MQ10 - 30型门机的现场实测 ,进行应力时间历程的统计及疲劳寿命分析 。
About the cracking of portal Crane structures, An assng and torsion as crack creatire life is made. The result including practice measurement of a MQ10-30 portal crane in a port, the statistic of stress-time history and the fatigue life analysis demonstrated the basic agreement of the mechanical model with practice.
