仿鱼罩式无动力捕获装置设计与分析

Design and Research of Bionic Fishing Hood and Unpowered Capture Device

针对复杂海况下水下装备的捕获问题,根据传统捕鱼罩结构形式,提出了一种面对点捕获方式,设计出具有锁紧与解锁功能的四连杆捕获机构,开发出由支撑外壳和四连杆捕获机构组成的新型仿鱼罩式无动力捕获装置。基于RecurDyn、Adams、Workbench环境,对捕获系统进行了运动学、动力学、有限元分析研究。研究结论表明,该装置可以在无动力条件下稳定地捕获水下装备,捕获过程方便、安全可靠;基于数字化设计分析技术为海洋工程装备开发提供了有益的探讨。

To the capture problem of underwater equipment in complex sea condition and according to the traditionalfishing hood structure, the face to point capture mode have been proposed. The four bar linkage mechanism with locking and unlocking function is designed. The new - type bionic fishing hood and unpowered capture device which is made up of the support shell and the four bar linkage capture mechanism has been developed. Based on the environment of RecurDyn, Adams and Workbench, kinematics, dynamics and finite element of the capture system are studied. Research results show that the device can capture underwater equipment stably and the capture process is convenient, safe and reliable. The analysis technology based on digital design has provided beneficial discussion for the development of marine engineering equipment.
