The invention belongs to the field of low-speed wind tunnel tests, and discloses an active simulation wind tunnel test method for a wake flow field of an oiling machine, and the method comprises the following steps: 1, determining an initial trailing vortex circular rector and a trailing vortex initial vortex nucleus distance in a model; step 2, installing an active simulation generation device for the wake flow field of the oiling machine; 3, a flow field calibration mechanism is installed; step 4, starting a wind tunnel and an oiling machine wake flow active simulation generation device, starting a hot-wire probe to carry out acquisition, and measuring and calculating a flow field velocity circulation; 5, calculating a rotating speed gain coefficient to simulate a target refueling machine wake flow field, and calculating to obtain a rotating speed control gain coefficient K according to the circulation data; starting the wind tunnel to a specified wind speed, controlling the rotating speed of the motor to be stabilized to a corrected rotating speed N, and generating a target refueling machine wake flow field in the test area. The oiling machine wake flow field can be simulated in the wind tunnel environment, and the problems that wake flow field simulation is prone to distortion and sensor arrangement cannot be carried out due to the fact that wind tunnel size is limited in an existing oiling machine wake flow field direct simulation test are solved.
