电气化铁道用铜及铜合金接触线反复弯曲试验方法的研究

Research on the Bending Experiment Method on Copper and Cuprum Alloy Contact Wires for Electrified Railways

在弯曲半径和工装夹具相同的条件下,对不同规格、不同种类国产接触线,在不同速度下进行反复弯曲试验,研究弯曲速度对接触线试验结果的影响。

Under the condition of same bending radius and same fixture Clamps, the authors do bending experiment for different types of contact wires made in China under different speeds, and research the influence of bending speed on contact wire experiment results.
