With the good performance and wide application of surface texture in various aspects, more and more scholars are devoted to investigating the effect of texture interface on tribological properties. Disc brake friction pair is a typical friction brake interface. In order to consider the influence of grooved brake interface on vibration characteristics during braking, a simplified finite element model of brake interface is established in this paper. By processing parameterized grooves with different lengths and angles on the surface of the brake disc, the effects of “blind groove”, “through groove” and “angle” on the vibration characteristics of the brake disc during braking process are simulated and studied, which can provide reference for the structural design and optimization of the brake disc texture.
