Design and Dynamic Simulation of Folding Wing Expansion Mechanism for Underwater Vehicle

College of Marine Engineering, Northwestern Polytechnical University, Xi′an, 710072, China

摘要: 为了适应水下航行器发射装置的尺寸限制, 满足水下航行器发射后的稳定性要求, 设计了一种水下航行器折叠翼展开机构。在对该机构进行力学分析的基础上, 建立了折叠翼展开过程动力学模型, 并通过数值仿真, 讨论了扭转展开机构设计参数和发射动力学参数等对折叠翼展开动力学特性的影响, 验证了机构设计的可行性与可靠性。该研究结果可对进一步优化和改进水下航行器折叠翼的设计方案提供参考。

Abstract: To adapt the size limit of an underwater vehicle launcher and meet the stability requirement of underwater vehicle after launching, an expansion mechanism of underwater vehicle folding wing is designed. Based on mechanical analysis, a dynamic model of the mechanism is established. The influences of the factors, such as the design parameters of the expansion mechanism and the parameters of launching dynamics, on the dynamic characteristics of this folding wing are obtained in different hydrodynamic conditions through numerical simulations. Simulation results confirm the feasibility and reliability of the mechanism design. This study may provide a reference for improving and optimizing design scheme of underwater vehicle folding wing.
