本文在前文基础上研究冷挤压钢管弹塑性变形和内力,计算弹、塑性极限载荷和钢管间的挤压力;讨论钢模与钢管摩擦系数对极限载荷的影响、最后给出计算实例.
Based on the above, the paper studies the elasto-plastic deformation and internal forces of cold-extruded steel tubes and calculates the elastic-plastic ultimate load and the compressive force between the steel tubes. The influence of the friction coefficient between steel mold and steel tube on the ultimate load is discussed. Finally, a calculation example is given.
