The invention discloses a steering-by-wire road feel simulator of a loader. The steering-by-wire road feel simulator aims at accurately detecting a rotation angle of a steering wheel and can provide adjustable appropriate road feel for a driver. Two ends of each of a left steering oil cylinder and a right steering oil cylinder are respectively mounted on a front vehicle frame and a rear vehicle frame through hinge pin shafts, and a left hydraulic control one-way valve and a right hydraulic control one-way valve are respectively linked with a left one-way valve, a right one-way valve, and pipelines between a one-way differential pressure sensor and the left steering oil cylinder and the right steering oil cylinder; a vehicle-mounted electronic control unit (ECU) is connected with the one-way differential pressure sensor through wires, an axial angle encoder is connected with the vehicle-mounted electronic control unit(ECU) through wires, and a left electromagnet and a right electromagnet are connected with the vehicle-mounted electronic control unit(ECU) through wires; the left electromagnet and the right electromagnet are fixedly mounted on the rear vehicle frame, the axial angle encoder is mounted on a rotating shaft of the steering wheel in a sleeving manner and fixedly connected with the rotating shaft of the steering wheel, and a damp disk is fixed on the rotating shaft of the steering wheel in thread linkage and binding linkage manners. The steering-by-wire road feel simulator disclosed by the invention is suitable for generating the road feel for a steering-by-wire vehicle.
