The invention provides a device and a method for predicting a hysteresis characteristic model of a pipe bus support telescopic line clamp. The device comprises a bearing device, a loading device, a parameter measuring device and a data processing device, wherein the bearing device is used for holding the pipe bus support telescopic line clamp; the loading device is used for applying load to the pipe bus support telescopic line clamp; the parameter measuring device is connected with the loading device and the bearing device and is used for measuring the load applied to the pipe bus support telescopic line clamp by the loading device, and the displacement of the pipe bus support telescopic line clamp which is driven to move under the action of the load; the data processing device is connected with the parameter measuring device, is used for receiving the load applied to the pipe bus support telescopic line clamp by the parameter measuring device, and the displacement of the pipe bus support telescopic line clamp which moves under the action of the load, and is used for confirming the hysteresis characteristic model of the pipe bus support telescopic line clamp according to the load and the displacement. As loads are applied to the pipe bus support telescopic line clamp repeatedly, the hysteresis characteristic model of the pipe bus support telescopic line clamp can be established, and the anti-shaking property of interconnecting equipment connected with the pipe bus support telescopic line clamp can be relatively well studied.
