The invention discloses a rail transit steel rail turnout polishing simulation test device and method, the rail transit steel rail turnout polishing simulation test device comprises a rotation unit, a reciprocating unit, a turnout swing unit and a pressurization unit, and the rotation unit comprises a grinding tool rotation mechanism, a temperature monitoring mechanism and a turnout grinding tool; the movable end of the grinding tool rotating mechanism is detachably connected with the turnout grinding tool through a torque sensor and used for driving the turnout grinding tool to rotate and monitoring the torque, and the temperature monitoring mechanism is used for monitoring the temperature in the grinding process. Through the reciprocating unit, the rotating unit, the turnout swinging unit and the pressurizing unit, four main influence parameters, namely the grinding tool moving speed, the grinding tool rotating speed, the grinding tool grinding angle and the grinding tool grinding pressure, which originally act on the turnout grinding tool in a combined mode are disassembled into four independent action parameters; and controllability and operability of each single parameter under laboratory conditions are improved.
