摘　　要：针对汽车起重机倾翻事故频发的现状,研究影响汽车起重机工作稳定性的主要因素。建立某300 t级全路面汽车起重机最大允许起重量与主臂长度、转台回转角、起重臂仰角关系的数学模型,基于该模型对影响汽车起重机工作稳定性的多种典型因素,如工作幅度、稳定系数、场地坡度、风载荷、惯性力、离心力进行分析,并进一步研究各因素的变化情况对汽车起重机工作稳定性的影响程度。In view of the current situation of frequent rollover accidents of truck cranes,the factors affecting the working stability of truck cranes are studied.A mathematical model of the relationship between the maximum permissible lifting capacity Gmax of a 300 t all-terrain truck crane and the main boom length L,rotating platform slew angle and lifting boom angle is established.Based on this model,a variety of typical factors affecting the working stability of truck cranes,such as working amplitude,stability coefficient,site slope,wind load,inertia force and centrifugal force,are analyzed,and the influencedegree of changes of each factor on the working stability of truck cranes is further studied.
