本文研究了在轴向压力和横向力的作用下,在变幅平面内,格构式变截面臂架的稳定性问题,导出了临界力的计算公式,对臂架模型进行了试验,并与模型计算结果作了分析比较。
In this paper, under the action of axial pressure and transverse force, the stability of the lattice-structure variable-section boom is studied in the luffing plane. The formula of the critical force is derived and the boom model is tested. The results of model calculation are analyzed and compared.
