摘　　要：在研究流动式起重机倾覆力矩及复原力矩的概率分布特性和干涉模型的基础上,导出不倾覆事件概率的解析解,提出流动式起重机稳定性的可靠性验算方法和验算准则。采用该验算方法和验算准则,可有效地判断流动式起重机的抗倾覆稳定性是否符合实际工况要求。Based on the interference model and the probability distribution of the overturn moment and the stable moment for ambulatory crane, the author derivates the probability solution of non -overturning event, puts forward a novel method and criterion for the reliability verification to the stability of the crane. The method adopted in this paper is available to ensure whether or not can the stability of the crane meet the requirements of the crane~ working.
