夹具对预应力钢绞线拉伸试验的影响及改进措施

摘要

通过理论分析比较V形夹具与半圆形夹具的不同，对比试验比较V形夹具和半圆形夹具对钢绞线最大力数值的差异，找到提高夹具夹持效果和检测数据准确性的措施。%Through the theoretical analysis of the difference between the V-type clamp and half-round clamp,and the contrast test to compare the influence of different fixture on the tensile test of steel strand,then found the measures to improve the accuracy of the data.
