Abstract

The invention discloses a vertical swing-rod holding device applicable to low-frequency internal-friction measurements. The vertical swing-rod holding device mainly comprises a holding mechanism and an adjusting mechanism, wherein the holding mechanism is used for maintaining the horizontal direction, the adjusting mechanism is used for producing vertical displacement, the holding mechanism is connected with the adjusting mechanism in such a way that a bearing is matched with a bevel wheel groove, the deep groove ball bearing is arranged at the tail end of the holding mechanism, a wheel groove frame is arranged at the upper end of the adjusting mechanism, and the bevel wheel groove is arranged on the wheel groove frame. According to the method, the vertical swing-rod holding device applicable to low-frequency internal-friction measurements is skillful in design, simple in structure and low in manufacturing cost. The bevel wheel groove is matched with the bearing, so that the displacement of the adjusting mechanism in the vertical direction can be converted into position changes of the holding mechanism in the horizontal direction, and a clamping structure is pulled to achieve clamping of a vertical swing rod by a holding rod.

Description

technical field [0001] The invention relates to the field of detection auxiliary devices, in particular to a vertical swing rod clamping device suitable for low-frequency internal friction measurement. Background technique [0002] The measurement of low-frequency internal friction is done on a low-frequency mechanical spectrometer. The sample is placed upright, the lower end is fixed at the fixed end and cannot be adjusted, and the upper end is free and long and fixed on the vertical swing rod, which is connected and supported by the cotton thread on the support mechanism and balanced with a counterweight. Add a small cyclic stress (stress in the horizontal direction) to the free end, and then measure the amplitude attenuation of the sample (free decay method) or the phase angle of the strain lagging behind the stress (forced vibration method) to measure the internal friction value. This requires that the centerlines of the fixed end (lower end) and the free end (upper e...
