摘要
[目的]为了研究船舶在航道正常航行中突发设备故障导致紧急搁浅的情况,避免更大交通事故和灾难的发生,对其搁浅状态及后续脱浅评估进行深入研究。[方法]以某型20万t散货船为研究对象,其在铜鼓航道航行时,由于失控需要驶向航道边坡主动搁浅。根据船体型线建立有限元网格模型,考虑船舶的航行状态、河流及泥沙的力学性能参数,基于任意拉格朗日-欧拉算法(ALE)方法进行船舶-河水-泥沙的流-固耦合仿真;分析船舶的动力学响应,以及航行速度、位移的演化历程,预测船舶的最终搁浅状态。[结果]基于搁浅仿真以及理论分析,对研究的20万t散货船的脱浅受力进行评估,为后续的安全救援提供理论指导。[结论]相关研究可以为航行安全、航道疏通等工程问题提供预报和解决措施。
[Purpose]The aim of this study is to investigate the emergency grounding of ships caused by sudden equipment failures during normal navigation in channels,in order to prevent larger traffic accidents and disasters,and to conduct in-depth research on grounding states and subsequent grounding release assessments.[Method]A 200000 t bulk carrier is taken as the research object.During its navigation in the Tonggu Channel,it was required to actively ground on the channel slope due to loss of control.A finite element mesh model is established based on the hull lines,considering the ship's navigation status,the mechanical properties of the river and sediment,and using the ALE method for fluid-structure coupling simulation of the ship-water-sediment system.The dynamic response of the ship,as well as the evolution of navigation speed and displacement,is analyzed to predict the final grounding state of the ship.[Result]Based on grounding simulation and theoretical analysis,the grounding release forces on the 200000 t bulk carrier are evaluated,providing theoretical guidance for subsequent safety rescue operations.[Conclusion]The relevant research can provide forecasts and solutions for engineering issues such as navigation safety and channel clearance.
