| 摘 要： | 为推导一种新的机械自紧厚壁圆筒塑性半径的计算公式,首先采用ANSYS对不同摩擦系数的机械自紧进行数值模拟,发现摩擦系数对残余应力和塑性半径无影响,因此在推导塑性半径计算公式时可不考虑摩擦系数的影响；其次根据机械自紧过程中冲头圆柱段和厚壁圆筒接触处径向应力相等推导出了塑性半径的计算公式.利用该公式计算了9个不同模拟管的塑...

| Abstract: | To derive a new formula to calculate the plastic radius of autofrettaged thick-walled cylinder,some simulations were run for different friction coefficients.It was found that the friction coefficient did not influence the residual stress and plastic radius.Thus,it is unnecessary to consider the effect of the friction coefficient in deriving the new formula of plastic radius.Also,considered that the radial stress in contact section of swage and thick-walled cylinder are equal during the swage procedure,the f... |
