Bionic innovation design of disc brake

Creative thinking is the key factor of the product innovation design, and Bionic interaction design is a completely new method to achieve the creative design. In order to increase the abrasion resistance and reduce the natural frequency of automobile disc brake, and then weaken the brake squeal, the brake is designed from bionic points. Firstly, the brake is modeled at four levels of the function, principle, behavior and structure to fully express the internal relationship of the product; similarly, the corresponding biological system is modeled with function, strategy, action and structure based on the HIM. Meanwhile, considering the synergistic effect of multiple organisms, a multi-level Cooperative Mapping Mechanism based on multi-biological principle is raised to design the brake scheme. Secondly, thermodynamic and modal analysis of the bionic brake scheme is done. Finally, the bionic structure is parameterized designed based on numerical simulation to verify the feasibility and effectiveness of the proposed method.
