Experiment research on foil movement of bionic propulsion

通过模仿水母在水中的推进方式,设计一种新型仿生推进装置。为获得装置的推进性能,前期对翼盘在不同工况下的力学特性进行仿真分析,在此基础上设计翼盘变速运动试验方案,开发推进装置性能测试平台,采集试验样机在不同驱动频率下的试验数据,并对结果进行比对分析。研究表明:该试验能够较精确地反映推进装置参数对其推进性能的影响,其中位移测量结果能够真实反映翼盘在静水中的运动规律,力学测量结果为推进装置结构的进一步优化提供依据。

The configuration of new bionic propulsion device was designed after observing the movement of jellyfish and analyzing morphological changes in the process of generating thrust.In order to obtain the performance of the device,a testing platform was devised and developed to collect experimental data at different working conditions.The results indicate that the experiment is able to get the influence of propulsive performance with different parameters.The movement rule of leaf is reported by measuring its displacement.And the data of mechanical characteristics provides a criterion for propulsion unit design and structure optimization.
