本文提出一种直接根据测定的应力值推算车架节点双力矩的简便方法。由此还可求得在约束扭转工况下各载荷分量所引起的剪应力,最后举一实例予以阐述。 This paper presents a simple method to calculate the double moment of frame node directly based on the measured stress value. From this it is also possible to find the shear stress caused by the load components under the restrained torsion condition. Finally, an example is given to illustrate this.
