The control method of hourglass mode in the simulation of the squeezing of ocean cable
Abstract:The hourglass mode generated in the simulation of ocean cable side squeezing, made a serious influence on the accuracy and reliability of the analysis results. The effective control method of the hourglass mode for the whole cable is a important thing in the analysis. Firstly this paper find out which components have the serious hourglass mode . Then several control methods of the hourglass mode were studied and analyzed, the most effective control method was concluded and a more accurate result was got.
Keywords: Ocean cable Simulation Hourglass mode Control methods
