一、前言本文介绍一种新型金属丝材弯曲、扭转自动试验装置及其相应的试验方法。试验装置可以自动记录金属丝材、片材悬臂弯曲试验时的弯曲角——弯曲力矩曲线及弯曲回复曲线;扭转试验时的扭转角——扭转力矩曲线及扭转回复曲线。根据这些实验曲线可以计算出试验材料的一系列力性参数,文中提 I. Introduction This article describes a new type of wire bending, twisting automatic test device and its corresponding test method. The test device can automatically record the bending angle-bending moment curve and bending recovery curve of the metal wire and the sheet cantilever bending test, the torsion angle-torsion torque curve and the torsion recovery curve during the torsion test. According to these experimental curves can be calculated a series of mechanical parameters of the test materials, the text mention
