| 摘 要： | 对渔船锚泊时的锚链动力负荷问题进行了分析．在考虑风、浪、流影响的基础上，建立了锚链动力变形方程，着重分析了二阶波浪力导致的相当高的系泊张力．针对钢丝绳及有档电焊锚链，分别计算了其在特定海况下的最大拉力，为工程设计提供了一定的理论基础．

| Abstract: | The dynamic forces acted on the chain cable of mooring fishing ships is investigated. Taken the effects of wind wave current into account, the dynamic equation of the chain cable is derived and the mooring force led by the second order wave force is analyzed specially. Aimed at the welded chain cable and steel wine rope, their maximum tensile force is computed respectively under specified sea conditions. The analysis lays the foundation for engineering designs. |
