The equations of motion based on multibody system dynamics are derived. Furthermore, it can model the block loader that distributes the tension in wire ropes between the lifted module and the block loader equally, and link beams that are used to connect hooks by hinge joints. This program is focused on reducing modeling time, while increasing modeling accuracy.
Due to the limitations of the existing dynamic analysis programs, we develop a differentiated program that is dedicated to the mega floating crane.
