Multifunctional friction-wear testing machine

The invention provides a multifunctional friction-wear testing machine, which relates to the technical field of friction-wear, and comprises an upper friction mechanism for driving an upper sample to move in the x direction, and a lower friction mechanism for driving a lower sample to rotate, the loading mechanism is arranged below the lower friction mechanism, and the loading mechanism applies loading force to the lower sample; the speed sensor is used for detecting the linear motion speed of the upper sample mounting rack; the friction torque sensor is used for detecting the friction force between the upper sample and the lower sample; reciprocating type and pin-disc type friction wear tests can be achieved through one device, the upper sample is driven by the first servo motor to reciprocate, the lower sample is driven by the second servo motor to rotate, and the friction wear resistance of the upper sample is improved. The upper sample and the lower sample are subjected to reciprocating opposite grinding
