Reciprocating friction testing machineIt is a precision instrument used to simulate the wear resistance, friction coefficient, and wear amount of materials under reciprocating friction conditions. By setting parameters such as load, frequency, and stroke, it reproduces the friction and wear process of materials in actual use. It is widely used in materials science, mechanical manufacturing, automotive industry, coating technology, and other fields. It is the core equipment for evaluating the surface performance and reliability of materials.

　　Reciprocating friction testing machineThe working principle of is mainly based on the physical processes of friction and wear. Its core components include the drive mechanism, load loading mechanism, reciprocating module, friction pair clamping mechanism, etc. The specific workflow is as follows:

Drive mechanism: The spindle is driven by a motor, and the rotational motion is converted into reciprocating motion through a crank slider mechanism. The test piece is installed on the bracket and moves along with the bracket.

Load loading mechanism: The working load is generated by the gravity of weights or an automatic loading system, and is applied to the specimen through elastic support arms or compression springs.

Reciprocating module: By adjusting the eccentricity of the eccentric disc, the reciprocating stroke of the specimen can be adjusted within a certain range. Variable frequency speed regulating motors can achieve arbitrary adjustment of friction speed, making it convenient to simulate the actual operating speed.

Friction pair clamping mechanism: The friction pair adopts standard ball friction, pin disc friction, and other forms, which can realize the selection of various friction pairs such as ball disc pin disc reciprocating, rotating, and ring ring friction.

Data collection and analysis: The other end of the elastic support arm is close to the displacement sensor, and its vertical displacement reflects the change in wear of the specimen. By measuring the friction force with strain gauges attached to the elastic arm, the change in resistance of the strain gauges is converted into a change in voltage, and the value of the friction force is obtained after calibration.
