Based on the idea of bionic coupling, three kinds of clutch friction pads with bionic characteristics are designed, namely: circular pit friction pad, straight groove friction pad and wavy groove friction pad, respectively. Both of the complex eigenvalue analysis and explicit dynamic analysis are performed by using ABAQUS, to study the vibration properties of the clutch system from two aspects of frequency domain and time domain. Complex eigenvalue analysis results show that the friction-induced vibration generated from the clutch system during engagement is characterized by multi-frequencies and it exhibits the superposition of multi-frequencies vibration response. With the increase of friction coefficient, the vibration intensity of the clutch system increases gradually, and the number of the vibration frequency increases as well. The results of the tendency of instability (TOI) analysis show that the bionic friction pad can effectively reduce the vibration tendency of the clutch system, especially in the case that the pad surface is processed with wavy grooves. Friction pad surface with wavy grooves exhibits the best ability in improving the vibration of the clutch system. Explicit dynamic analysis results show that the vibration amplitude of the clutch system decreases visibly when the friction pad is treated with bionic design, especially for the pad with wavy grooves, the corresponding vibration amplitude of the clutch system decreases significantly. By analyzing the interface stress of different friction pads, the results show that the bionic friction pads can improve the stress concentration phenomenon at the friction interface, which causes the stress distribution become more uniform, and accordingly weaken the energy accumulation generated from the friction interface. Especially for the case that the pad surface is machined with wave grooves, the stress amplitude of friction interface is the minimum, indicating that the clutch system has the best ability in keeping stable. This study provides a theoretical basis and a new idea for the bionic design of the friction pad surface to improve the vibration problem of the clutch system.

Three kinds of non-smooth bionic surface are manufactured on the brake disc surface, namely: surface groove disc, surface pit disc and surface groove with pit disc. Finite element analysis is performed by using ABAQUS to study the relationship between these three kinds of brake discs and brake system stability. Results show that the vibration modes of the brake are mainly reflected as the in-plane and out-plane vibration of the brake disc, accompanied by the bending and torsional motion of the brake clamp and the brake pad. Complex eigenvalue analysis is used to calculate the Tendency of Instability (TOI) of brake system, it is found that the squeal tendency of the brake system has significantly changed after the non-smooth bionic surface treatment. Specifically, the surface groove with round pit disc has the best potential in improving the stability of brake system, while the surface groove disc has the weakest effect among them. In addition, transient dynamic analysis is performed to verify the above results, it is found that the vibration acceleration amplitude, elastic displacement amplitude and interface force strength are reduced after dealing with the disc surface, and the surface groove with round hole treatment shows the most effective in reducing the squeal instability of brake system. However, due to the edges of grooves and round pits may form stress concentration areas, which will cause the damage of the edges in a certain way, thus it is suggested that the polishing process can be used to improve the surface life.
