A friction electrification test device

Abstract

The invention discloses a friction electrification test device. The loading mechanism includes a vertical loading plate, a horizontal loading plate and a connection assembly. The connection assembly includes a fixed block, a connecting rod, an upper spring and a lower spring; the upper sample clamp includes an upper sample and the fixture connector, the fixture connector is installed on the lower part of the horizontal loading plate through a three-dimensional force sensor, the upper sample is detachably installed on the bottom of the fixture connector, and can move horizontally; the lower sample is located below the upper sample and It rotates under the drive of the rotating mechanism; the electric measuring clamping mechanism includes the electric measuring brush head and the electric measuring support. The invention realizes a more stable load, can freely replace the type of sample fixture, adapts to various test conditions, and integrates an adjustable triboelectric measuring device, which has the advantages of simple measurement, easy manufacture, high experimental accuracy, and universal application Strong and modular replaceable advantages.

Description

technical field [0001] The invention relates to the field of testing devices, in particular to a triboelectric testing device. Background technique [0002] In real life, the phenomenon of triboelectrification is ubiquitous. Between parts in contact with each other, due to continuous contact separation or friction, charge transfer occurs at the interface between the two. On the one hand, the transferred charge has a wide range of applications and good prospects in mineral processing, dust removal, and triboelectric nanogenerators. On the other hand, it will also bring harm to industrial production and the protection of aerospace precision instruments. At present, there is a lack of testing machines on the market that can directly measure triboelectricity, so it is necessary to design a triboelectrification test device to accurately measure the electrical characteristics such as the amount of charge, current, and voltage generated during the friction process, so as to measur...
