Mixed motion type friction-wear test device

The invention discloses a hybrid motion type friction wear test device, which adopts double power source output, takes a stepless speed change motor as a first power source, adopts structures such as a belt, a cam shaft, an eccentric wheel and a piston cylinder to realize simulation of impact load motion, and simultaneously utilizes the same motor as the power source output through a clutch structure. One motor serves as a first power source to achieve rotary motion, then the mixed motion of impact and rotation is achieved through a square shaft, a roller bearing and other structures, the other motor serves as a second power source and is connected with a speed reducer, and an incomplete gear and rack structure is adopted to enable a friction disc to complete repeated transverse motion; the three kinds of motions realize single motion or mixed motion through structures such as a power switch or a sliding shaft sleeve, the motion conditions of various shaft or pin parts in different working environments can be
