Experimental device and experimental method for simulating deformation of sucker rod

The invention discloses an experimental device and an experimental method for simulating deformation of a sucker rod. The device comprises an oil supply cavity, a liquid supply cavity, an air supply cavity, a mixing cavity and a metering cavity, an oil pumping unit, an oil pumping rod and an injection pump; and a camera device, a data acquisition control panel and a central controller. The central controller analyzes deformation of the sucker rod at different time points through image recognition according to the operation conditions, shot by the camera device, of the sucker rod and the transparent tubular pump; the method comprises the following steps: continuously shooting fluid flow images in a transparent shaft through a camera device, and testing and analyzing speed distribution of a fluid flow field by utilizing particle image velocity measurement; and the liquid production capacity and the motor power are analyzed through data acquired by the data acquisition control panel.
