Analysis of the Deep Sea Mining Pipe Transverse Vibration Characteristics Based on Finite Element Method

This paper analyzes the transverse vibration laws of 5000 m ladder-shaped mining pipe under different towing velocities and accelerations in ocean, thinking as beam model, discretized based on FEM. The algorithm is used to solve problem obtain law. research shows that overall trend decreases first then increases, minimum value occurs at 3000 m, maximum top. Increasing velocity, acceleration, ore bin weight will increase value. intensity produced by same acceleration constant deceleration stages different, damping effect after adding also different. In range 0.01 m/s2–0.1 m/s2, reduction stage more significant, 0.1 m/s2-0.2 significant. or deceleration, when damping, generated large still far greater than small so ship should keep for motion.
