Simulation of crane load motion trajectory based on Unity 3D

Abstract

In order to simulate the crane motion load under wind and wave interference, the crane-load dynamics model is established by using the Lagrange equation and the inverse kinematics of the robot, and the numerical simulation is used to simulate the crane's trajectory. The Unity 3D is used to simulate the motion of the marine crane and the hanging object. The simulation results show that the ship crane suspension system exhibits chaotic motion under wind and wave disturbance, and the distribution range of the moving target in the three axial directions of the inertial coordinate system is about the same. To lay the foundation for the next step to establish a simulation training system for marine cranes.
