Purpose: The alteration of tooth surface microtopography has an influence on the dynamic behavior of gear transmission. In order to obtain accurate dynamic analysis results, a dynamic model of gear transmission with tooth surface roughness characteristics is required. Methods: A dynamic model of gear transmission with tooth surface roughness characteristics is established by employing fractal theory. Moreover, gears with varied roughness are measured and the corresponding transmission errors are obtained via simulation computation based on the collected data. Results: The numerical simulations demonstrate that the dynamic properties of the gear transmission gradually degenerate with the enhancement of the roughness. Moreover, the initial gear backlash has a little effect on the dynamic behavior of the gear, but has an effect on the impact strength when it meshes in and out. Compared with the traditional dynamic model, the model established in this paper has a better predictive capability. The experimental outcomes demonstrate that the dynamic behavior of the gears attenuates with the increment of the tooth surface roughness. Comparison with existing experimental data reveals that the simulation outcomes agree with the experimental findings in the frequency range from 0.2 to 0.6 as well as from 1.2 to 1.4. In the interval from 0.6 to 1.2, the simulation results follow the experimental data to a certain extent, with a generally consistent trend. Conclusions: This paper theoretically substantiates the correlation between tooth surface roughness and the dynamic behavior of gear transmission, establishing a foundational theoretical base for the design of gear surface.
