针对我国港口和电厂煤码头多次门机主臂架折断事故，从现象分析入手，确定其均为局部失稳而引起整体破坏。
The analysis made in the paper shows that many accidents on the portal cranes furnished to the harbours and power plant coal wharfs in China are caused by the buckling in their main jibs.
非线性屈曲分析结果较之特征值屈曲分析结果更能反映实际情况，得出当吊篮载荷分别为12058N和10126N时，臂节4和伸缩臂会发生局部失稳现象。
The nonlinear buckling analysis is sufficient to simulate the actual situation, draw telescopic arm section 4 and the overall buckling load when the hanging baskets were 12058N, and 10126N.
