Abstract
Dynamic analysis for the lateral movement of a lifting pipe in deep sea mining is made by using nonlinear finite element method. The factors influencing the dynamic stress and deformation of the lifting pipe are analyzed in detail by means of AD IN A. A new concept of ‘displacement delaying time’ is put forward and related influencing factors are also discussed. The results obtained are of great importance to the design and operation of the lifting pipe.
Keywords
