Structural strength and modal analysis of pile frame of 128m pile driving vessel

The pile frame on 128 m pile driving vessel is analyzed with a 3D pile holder model by ANSYS.It carries out the simulation of component stress and structural response under the two working conditions,lifting cargo with wind and laying towage,and check of the overall strength and stability of pile frame,as well as the modal analysis of pile frame structure.The simulation results show that the material strength of pile frame under the above two working conditions can meet safety requirements,which provide suggestion for the operation of pile frame based on the obtained results.
