摘　　要：为了掌握仿生柔性胸鳍动态摆动过程真实的水动力特性,研制了仿生多鳍条的柔性胸鳍模型及驱动控制系统,首次采用拖曳水池测力试验的方法对仿生柔性胸鳍摆动过程受力进行了测试,获得了柔性胸鳍在不同运动参数的受力数据,掌握了频率、摆幅、相位差等对仿生胸鳍模型受力的影响规律。试验结果表明:胸鳍摆动频率越大、摆幅越大,胸鳍产生的推力、侧向力和转动力矩越大;胸鳍鳍条间的相位差越小,胸鳍产生的推力、侧向力和转动力矩越大;柔性胸鳍不规则形变导致推力峰值不对称。In order to investigate the hydrodynamic characteristics of bionic flexible pectoral swing locomotion,the bionic multi-fin flexible pectoral model and drive control system were developed,and the hydrodynamic experiment was carried out in towing tank for the first time interiorly.The test data in different locomotion parameters were obtained and the influence rule of frequency,swing angle,and phase difference was revealed.The result of experiment indicates that,the higher the frequency is,the bigger the swing angle and the smaller the phase difference will be,and that the greater the thrust and the greater torsional moment will be obtained and the irregular shape change will lead to asymmetric appearance of the thrust peak.
