Research on Lightweight Design Method Based on Biological Knowledge Acquisition

In recent years, some countries have paid more and more attention to environmental protection and sustainable development and have been looking for new energy sources to replace non-renewable energy sources. Lightweight design is one of the ways to reduce energy consumption, but traditional lightweight design methods lack innovation in the principle of the product. Since the biological structure in nature always evolves in a way that minimizes energy consumption, this paper proposes a lightweight design method based on the acquisition of biological knowledge. By transferring biological knowledge to engineering design, we use the unique characteristics of biology to meet our design goals. First, some keywords are extracted from the design requirements of the target object and are expanded in the context of biological knowledge. Then, the expanded keywords are used to retrieve biological information in Asknature. Finally, python crawler is used to obtain biological knowledge to improve and optimize the target object and to achieve lightweight design. In this paper, a bionic design of the part reel in the fishing equipment winch is carried out, and the traditional reel and the improved reel were modeled, simulated and compared to verify the effectiveness of this method.
