本文叙述无梁叉管的特点,用旋转薄壳理论作近似计算的方法,并以无量纲形式给出应力系数表,以便简捷地确定控制性部位的应力值,文中还将计算结果,试验值及有限元分析成果作出比较,论证计算方法及附表可用于工程设计。 This paper describes the characteristics of beamless fork tubes, uses rotating thin shell theory as a method of approximate calculation, and gives the stress coefficient table in a dimensionless form, so as to simply determine the stress value of the controlled part. The results will also be calculated in this paper. The comparison with the results of the finite element analysis, demonstration of calculation methods and schedules can be used for engineering design.
