A grinding simulation test device and method for a steel turnout rail of rail transit are provided. The device includes a rotary unit, a reciprocating unit, a turnout swinging unit, and a pressurizing unit. The rotary unit includes a grinding tool rotary mechanism, a temperature monitoring mechanism and a turnout grinding tool. A movable end of the grinding tool rotary mechanism is detachably connected to the turnout grinding tool through a torque sensor, to thereby drive the turnout grinding tool to rotate and monitor a torque. The temperature monitoring mechanism is configured to monitor temperatures during a grinding process. Through the reciprocating unit, the rotary unit, the turnout swinging unit and the pressurizing unit, four main influencing parameters, namely, moving speed, rotary speed, grinding angle and grinding pressure of a grinding tool, are disassembled into four independent parameters, thereby improving controllability and operability of each single parameter under laboratory conditions.
