Abstract

The invention relates to a lever loading type friction wear tester for controllable magnetic field environment. The tester comprise a magnetic field device, a lower sample piece is arranged in the magnetic field device, a driving mechanism drives the magnetic field device to reciprocate in the horizontal direction, a loading rod is arranged above the lower sample piece, a test steel ball is arranged at the lower end of the vertical loading rod, and abuts against the upper plate surface of the lower sample piece, the loading rod is arranged at one end of a lever, a level body is hinged onto anadjusting base, the two ends of the level are provided with counterweights respectively, and a strain gauge sensor is arranged on one side of the lever in the length direction and is used to collect torsion of lever deformation and transmit the torsion into a computer. According to the friction wear tester, an electromagnetic coil applies a magnetic field to a contact area of a friction pair, thelevel is used for loading to improve the loading stability, experimental parameters including the load, the relative movement speed of the friction pair and magnetic field intensity can be changed atthe same time, and friction characteristics of different friction pairs can be tested and analyzed.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a lever-loaded friction and wear testing machine with a controllable magnetic field environment. Background technique [0002] Friction is ubiquitous in life, and tribology also exists as a basic science on the theory and practice of mechanical systems, and it is the study of the friction behavior between surfaces that interact with each other in relative motion. The existence of friction is sometimes beneficial and sometimes harmful. Any two relatively moving workpieces will produce friction when they contact each other. With friction, wear will inevitably occur. In order to reduce the wear between friction pairs, we often use adding lubrication The way to reduce the frictional resistance, so as to protect the friction pair. There are also various types of lubricants, which can be classified into solid lubricants, liquid lubricants, and gas lubricants according to the...

However, there is little research on the friction and wear testing machine designed for the working environment where the magnetic field exists. The present invention takes this as the starting point, and develops a reciprocating friction and wear test that can apply a controllable magnetic field for the existing experimental conditions of the magnetic field. It has the functions of variable load, variable speed, etc., and simulates a variety of magnetic field conditions. This design provides new ideas for the design of specific functional testing machines. It not only enriches the types of friction and wear testing machines, but also explores the existence of magnetic fields. Effects on friction experiments offer practical possibility
