The invention provide a method for testing fluid resistance on a material surface, which comprise that following steps: preparing a plurality of experimental sample, clamping the experimental samples, and setting initial test conditions; Adjusting the position of the slider so that the slider is located at the first end of the linear guide rail; Start the laser rangefinder to start ranging and drive the object, so that it can work in one of three working modes: setting the driving energy consumption mode, setting the traction driving force mode or setting the traction speed curve mode; Record the real-time traction force value fed back by the force sensor of the driving object in the whole process; And then stopping the ranging of the laser rangefinder; Test data processing and analysis; Repeat the above steps to obtain multiple test results. According to the invention, the surface turbulence resistance and surface microstructure drag reduction effect of experimental samples can be accurately tested, and the fluid drag reduction effect of different samples under different fluid environments and different rushing postures under different setting driving energy consumption, setting pulling driving force and setting traction speed curves can be tested.
