作为动力机械,螺旋桨的性能直接关系到船舶的运行状况。当船舶航行时,螺旋桨出现激振力异常的情况,会增大船舶的振动,导致船体不稳,若是风浪比较大,则可能引起倾覆。因此,对螺旋桨的振力异常情况进行及时准确的预报显得尤为重要。为实现这一目标,可依托云计算环境,借助适宜的软件,对螺旋桨激振力的产生过程加以计算,为异常数值预报分析提供可靠依据,这对于船舶航行安全性和稳定性的提升具有重要意义。
As a power machine, the performance of the propeller is directly related to the operation of the ship. When the ship is sailing, the abnormal excitation force of the propeller will increase the vibration of the ship and cause the hull to be unstable. If the wind and waves are relatively large, it may cause capsizing. Therefore, it is particularly important to timely and accurately predict the abnormal vibration of the propeller. In order to achieve this goal, relying on the cloud computing environment and with the help of appropriate software, the generation process of the excitation force of the ship propeller can be calculated to provide a reliable basis for the abnormal numerical prediction analysis, which is of great significance to the improvement of the safety and stability of the ship's navigation.
