load head

The punch load of nickel plated steel strip and steel strip was compared,and the surface morphology of inside wall of circular cups with different stamping depths was analyzed.

在RG2000型微机控制电子万能试验机上对镀镍钢带进行冲压成型试验,研究了镀镍钢带在不同压边力作用下的成型性能,对比了镀镍钢带与未镀镍钢带在冲压成型中所需的冲头载荷,对不同冲压深度杯形件侧壁内表面形貌变化做了比较研究。

Through analysis it is concluded that for a given rock and given tooth profile,the cut-in displacement(depth)is in a linear relationship with cut-in load,the volume of breaking pit decreases with t.

对试验结果进行分析,得到了围压作用下对于所试验的岩石和齿形,压入载荷和压入位移成线性关系;岩石破碎坑的体积随压入载荷的增加而减小;在以相同齿形压入相同岩石的条件下,岩石的破碎面积和体积随围压的增加而减小。
