Abstract

The invention discloses a turntable type multi-sample synchronous friction abrasion testing device which comprises a sample table, a fixing device, a driving device, a friction pair, a loading device and a friction coefficient measurement device, wherein the friction coefficient measurement device consists of a frictional force sensor, a variable power source, a signal acquisition circuit, a computer and a resistor chip. The connecting relationship is that the sample table is fixed on the driving device through the fixing device; the input end of the frictional force sensor is connected to the loading device, and the output end of the frictional force sensor is connected with the computer; two output ends of the variable power source and the input end of the signal acquisition circuit are respectively connected to the sample surface and the sample table; the output end of the signal acquisition circuit is connected to the computer; the resistor chip is attached to the sample. The invention also provides a corresponding testing method. The testing device is easy to mount and high in practicability, the friction abrasion conditions of different materials under the same parameter can be synchronously measured, the test material is saved, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to a wear test device, in particular to a rotary disc type multi-sample synchronous friction and wear test device and a test method thereof. Background technique [0002] Tribology is one of the most important disciplines in contemporary engineering science. What is the performance of a new material, especially when the working environment is harsh? Need to investigate. At present, there are many kinds of friction and wear testing machines with ball-on-disk structure or pin-on-disk structure, but most of them can only test a single sample, and their utilization rate of test materials is not high. When comparing different samples, the test period longer. For example, when analyzing a ball-disk friction and wear test, we found that the sample is a disc with a diameter of 6 cm, which is fixed on a slightly larger disc-shaped sample stage and driven by a motor to rotate. 6 mm diameter steel ball or pin) and the sample contact area ...
