预应力钢绞线拉伸试验中新型夹具的研究

Study on new clamping apparatus using for the tensile test of prestressed steel wires

新型夹具是为预应力钢绞线拉伸试验专门设计的，它解决了Ｖ 型夹具对钢绞线夹持不均匀的缺陷，提高了试验结果的准确度。普通１００ｔ

New clamping apparatus is specially designed for the temsile test of prestressed steel wires.The ad vantages of using it are more distributing of the grip of V-type clamping apparatus to prestressed steel wires and improving the accuracy of the test results.It can also be used in ordinary type 100t universal testing machine for the test of prestressed steel wires.
