Abstract

The invention relates to a bionic underwater vehicle swing propulsion performance integrated test platform comprising a bionic fish oscillator used for simulating a tested bionic underwater vehicle; the power driving system is used for driving the bionic oscillator to swing in the water tank; the high-speed imaging system is used for acquiring a swinging form image of the bionic oscillator in the water tank; the PIV speed measuring instrument is used for acquiring the speed of a fluid flow field in the water tank under the swinging action of the bionic swinging device in real time; the data measurement system monitors the noise radiation characteristics of the bionic oscillator in the motion state in real time and monitors the dependent variable of the connecting rod in the motion state of the bionic oscillator in real time; the information control system is used for sending a synchronous trigger signal to the power driving system, the high-speed imaging system and the data measurement system and uniformly controlling the working states of the bionic swinging system, the high-speed imaging system and the data measurement system; and the information processing system is used for evaluating the comprehensive performance of the bionic swinging propeller by integrating the swinging frequency, the swinging amplitude, the noise, the stress and the speed of the bionic swinging device.

Description

technical field [0001] The invention relates to the field of bionic dynamics, and the specific engineering field of application is the field of accurate measurement of propulsion performance of bionic submarines. Background technique [0002] Bionic submersibles imitate the movement patterns of deep-sea fish, and have the advantages of low energy consumption, large maneuvering navigation, and low noise. They have potential application value in scenarios such as seabed detection, silent tracking, and large maneuvering navigation in complex hydrological environments. Building a bionic submarine vehicle propulsion performance test platform is a key step to improve the motion performance, control performance, and noise performance of bionic submarines, and provides experimental and theoretical basis for the development of bionic submarine vehicles with high propulsion performance. [0003] The propulsion performance test platform of the bionic submersible usually adopts high-spe...
