Rigid Body Dynamics

Projects by Thorstein R Rykkje

My Doctoral Project

The project aims to develop a data-informed simulation of ship rotation (pitch, yaw, roll) and translation (surge, heave, sway) induced by on-board crane motion, waves and wind, in an effort to anticipate crane operations.

Integrating the Processes of Mechanics

To simulate the physical strain and motion of the ship and crane I will endeavour to integrate the processes of mechanics. Finite element(FEM), Multi Body Dynamics(MBD) and Finite Difference (CFD).

Weather Data

To enable the data-informed simulation, I have a collaboration with StormGeo. They are very interested in the project and have granted me access to their weather data server. The simulation will access the server and give needed data on the wave and wind conditions for the vessel.

Experimental

I will build a ship model fitted with a working crane to test and validate the simulations in the wave tank at HVL

Knuckle

This project researches the motion and control of a ship mounted knuckle boom crane to minimize the pendulum motion of a hanging load.

ROV

This paper researches the motion of an ROV induced by the motion of the robotic manipulators, motor torques, and fluid buoyancy. The project was done in collaboration with Cooper Union in New York.

Stability

This paper deploys the Moving Frame Method (MFM) to analyze ship stability moderated by a dual gyroscopic inertial device.
