幂硬化厚壁筒冲头推力计算研究

RESEARCH ON MANDREL PUSH FORCE IN MECHANICAL AUTOFRETTAGE OF EXPONENTIAL MATERIAL THICK-WALLED CYLINDERS

利用塑性力学中的能量法，以幂硬化材料模型为基层，从微元体的力学分析入手，结合合理的假设，分析计算了机械自紧冲头推力问题。这为进一步深入研究机械自紧理论提供了有效的手段。

In this paper,based On the energy principal methcd.from mechanical analysis of element of lamina and reasonable assumption, ananalytical method is provided for studying calculation of the mandrel pushforce in mechanical autofrettage of exponential material thick-walled cylinders.It may be used for reference for further studying autofrettage technique.
