摘要

本仪器采用 FBM-3D-009型步进电机作动力源实现自控

电机转速分两段连续可调

第一段为1转/分～90转/分;第二段为110转/分～360转/分。剪位移的大小通过调节两个光敏二极管的距离来控制

精度达±0.01毫米。1～9999次的剪切次数可以预置

并可通过电子数码管不断地显示实际剪切次数。当剪切次数达到预置剪切次数时

自动停机

终止试验。另外

可通过手动开关

作人工控制。剪位移、剪应力可通过相应的传感器作自动记录。本仪器可做直剪快剪、松弛流变、疲劳剪切、单脉冲冲击等试验。

Abstract

This apparatus can be used for direct rapid shear tests

relexation rheological tests

fatigue shear test

single impulse test etc.

the movement of its shear box is automatically controlled by the step motor FBM-3D-009 of which the rare is divided into two ranges:1~90 and 110~360 circles per min

each being adjusted step by step. The adjustment of the shear displacement with precision up to ±0.01mm is reached by regulating distance between the two light-sensitive diodes. The shearing times within 1~9999 can be predetermined and displayed on digitrons one by one. If the shearing times are the same at the predetermined

shearing will stop automatically. Besides

the apparatus can be operated manually. In testing the shear displacement and the shear stresses are recorded automatically by means of the end instruments and the recording meter.
