During the gear meshing process, the driving speed plays a crucial role in evaluating mesh stiffness, a factor that many scholars often overlook along with the accompanying centrifugal effects. Based on Euler beam theory,a original computational algorithm was proposed to calculate the dynamic mesh stiffness of spur gears considering driven-speed effects by introducing centrifugal effects into the velocity field. Using the driving speed as a control parameter, the dynamic mesh stiffness in relation to driving speed was investigated, and the nonlinear relation between centrifugal effects and dynamic mesh stiffness was demonstrated. The results indicate that, under the influence of a centrifugal field, both the natural frequency and the dynamic mesh stiffness of the gears increase with rising driving speed. Additionally, materials with a high elastic modulus tend to suppress the impact of driving speed on dynamic mesh stiffness, while higher density has the opposite effect. The research results provide reference for further analysis of gear vibration and noise under centrifugal effects.
