Design of Bionic Batfish Based on Topology Optimization Method

Bionic batfish is a new type of unmanned underwater vehicle. It combines the advantages of low noise and low energy consumption of ocean glider, and low water resistance and high flexibility of bionic robotic fish. It has great significance in pelagic research and observation and deep-sea exploration. This paper first introduces the mechanical structure of bionic batfish, shows how topological structure optimization algorithm is applied to realize the optimal layout of each interior part, demonstrates that the design of hull is based on the form of batfish considering its high mobility, and exemplifies the approach of modularization in designing components; then it shows the analysis of the pressure resistant hull, and MATLAB simulation of different motion states of the bionic batfish, which lays a theoretical foundation for the later practical engineering application.
