摘要:
为研究铰接对浮体稳定性的影响,该文采用计算流体力学和多体动力学方法,提出基于粘性流理论的铰接多浮体仿真模型。采用有限体积方法,用重叠网格将波浪水池和浮体区域进行网格划分。将浮体视为刚体,浮体之间通过虚拟铰接约束成多浮体系统,建立仿真模型。实验研究发现,铰接浮体比刚性连接浮体更加稳定。仿真结果与实验结果对比,表明仿真模型中铰接约束的合理性和可靠性。
Abstract:
Based on the viscidity theory,a numerical model of hinged multiple floating bodies is presented using computational fluid dynamics and multi-body dynamics to study the influence of hinge constraint on the stability of floating bodies. Based on the finite volume method,the mesh of the wave tank and the floating structure is generated by using the overset mesh method. By considering the floating bodies as rigid bodies,a multiple floating bodies system is formed with the restraint of a virtual spherical joint,and a numerical model is built. Experimental researches show that the hinged multiple floating bodies are more stable than rigidly connected floating bodies. The simulation results are compared with the experimental results,and the rationality and applicability of the spherical joint are verified.
