Research on clamping force of wire saw for piles removal of process-based offshore discarded platform

Piles may be cut off by wire saw in the course of piles removal on a discarded platform,where the proper clamping force is precondition for wire sawing security and stability work.Then the wire saw work principle is introduced.And the external force is analyzed during wire saw clamping process as well as a process-based clamping force nonlinear mathematical model is proposed.Afterwards the mathematical model for clamping force is analyzed in theory,and the causal corresponding relationship of the various parameters in clamping force are explained.According to the wire saw actual work environment and the corresponding parameters,the wire saw clamping force is solved using the model,which result is compared with others.Finally the wire saw clamping device and hydraulic system are designed.
