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.
