Lubrication performance of kite-shaped microtexture under hydrodynamic lubrication

New kite-shaped textures are designed in this paper to improve the lubrication performance of tribological systems under hydrodynamic lubrication. Moreover, pressure distribution and load-carrying capacity of the kite-shaped textures under fixed working conditions are solved using Reynolds' equation based on the form of mass conservation. Lastly, the influence of kite-shaped textures on the friction coefficient under different geometric parameters is investigated. Moreover, a double-layer composite kite-shaped texture is designed, and the influence of parameters on lubrication performance is investigated. Numerical simulations and experiments are used to find the optimal parameters and effectively reduce the friction coefficient, thus providing a reference for reducing frictional wear in mechanical systems under full-film oil lubrication conditions.
