参变量积分在拉拔滑移线场中的运用

APPLICATION OF THE INTEGRATION DEPENDING ON A PARAMETER TO THE SLIP LINEFIELD OF DRAWING

摘要: 对断面减缩率ε=(H-h)/H=2sinθ/1+2sinθ的拉拔滑移线场边界滑移线引进参数方程并进行换元积分求得静水压力P的分布函数。模角θ=30°的计算实例表明上述方法求得结果与传统方法计算结果一致。

Abstract: A parameter equqtion has been introduced to the boundary slip line in the Drawing deformed zone with a fractional reduction ε=(H-h)/H=2sinθ/1+2sinθ and a distributed function of hydrostatic pressure P has been obtained using integration by substitution. An example for semicone angle of die θ=30° has been calculated by this method. It has been shown that the results from this method are the same with those from the conventional solution.
