The invention discloses a device and a method for measuring and calculating a side slip angle of an articulated vehicle, and relates to the technical field of vehicles, the measuring and calculating device comprises an inertial navigation system, a first optical fiber gyroscope, an angle acquisition unit and a processing unit; wherein the inertial navigation system acquires a gravitational acceleration component and an angular velocity of the articulated vehicle, the first optical fiber gyroscope acquires a rotation angular velocity of the rear vehicle body, the angle acquisition unit acquires a hinge angle between the front vehicle body and the rear vehicle body, and the processing unit processes the articulated vehicle according to the gravitational acceleration component, the angular velocity, the rotation angular velocity and the hinge angle. Indirectly measuring and calculating the side slip angle of the center of mass of the articulated vehicle; the problem that the side slip angle of the center of mass
