Abstract
Under the traditional dynamic model, the conventional method for
solving the rotation angle of a rigid body is to use the fixed-axis rotation law of
the rigid body, but the known rotation shaft position must be used as a prerequisite.
In practical work, for the rotation of a rigid body under multiple forces, solving
the shaft is often a difficult problem. In this paper, we consider the rigid body of
the disc is subjected to the force of uneven magnitude from multiple angles, the
position of the rotating shaft is obtained by iterative inversion through the rigid
body rotation law and the dichotomy method. After the position of the shaft is
determined, we establish a differential equation model based on the law of rigid
body rotation, the rotation angle of the rigid body thus being solved based on this
model. Furthermore, an optimization algorithm such as genetic algorithm is used
to search for a correction scheme to return the rigid body to equilibrium at any
given deflection angle. The model and method are based on computer to explore
the law of rotation, the practical application of them play an important role in
studying the concentric drum movement and the balance of handling furniture.
