截面型式对伸缩臂局部稳定性的影响

The Influence of Telescopic Crane Boom Section on Boom's Local Stability

对四边形、六边形截面伸缩臂的稳定性计算方法进行了探讨。编制了相应的计算程序 ,以 QY5 0汽车起重机为例 ,对不同截面形式五节伸缩臂稳定性进行了计算 。

A computing method was developed to calculate the stability of quadrilateral, hexagon booms and the computing procedure was programmed in FORTRAN to calculate the stability of various boom shapes of telescopic crane. The stability factors of varied section boom for QY50 crane were also calculated. \;
