摘　　要：为实现蟹笼渔船蟹笼挂钩自动脱钩,设计一种撞击式自动脱钩装置。首先,利用三维软件和TRIZ理论对脱钩装置进行结构设计与改进。然后,基于Ansys workbench对脱钩装置在不同工艺参数下对撞击过程进行仿真模拟,通过仿真试验所得数据分析不同工艺参数对撞击效果的影响,以撞击角度和撞击速度对装置的工艺参数进行优化。最后,进行实验室试验来验证仿真试验所得参数的可靠性。结果表明:当牵引速度为40 m/min、撞击装置的上扬倾角为15°时,挂钩所受最大法向力为242.75 N,实测脱钩率为100%。该研究验证显示动力学和中心复合设计理论结合所得工艺参数的可靠性和精确度,为未来撞击式结构设计分析和参数选取提供一定的参考。In order to realize the automatic decoupling of the crab cage hook on the crab cage fishing boat,a percussive automated decoupling device is designed.Firstly,the structure of the decoupling device is designed and improved by using three⁃dimensional software and TRIZ theory.Then,based on Ansys workbench,the impact process of the decoupling device is simulated under different process parameters,and the influence of various process parameters on the impact effect is analyzed by using the data obtained from simulation test,the impact angle and impact speed are used to optimize the device′s process parameters.Finally,the laboratory tests are carried out to verify the dependability of the parameters produced by the simulation experiments.The results show that when the traction speed is 40 m/min and the upward inclination angle of the impact device is 15°,the maximum normal force of the hook is 242.75 N,and the recorded decoupling rate is 100%.This research validates the dependability and accuracy of the process parameters produced by merging display dynamics with central composite design theory,and it provides a certain reference for future impact structure design analysis and parameter selection.
