Abstract:
To obtain the accurate and efficient numerical simulation algorithm for describing the rotation law of a fuze ball rotor,two kinds of fuze ball rotors are numerically simulated with the mathematical model of quaternion using the Runge-Kutta method and Gear method respectively.The simulation results show that compared with the strongly nonlinear mathematical model of Euler angles,the linear quaternion model of the fuze ball rotor can avoid the singularity when the nutation angle approaches 0° or 180°.The time-consumed for the Runge-Kutta method is about one third of the Gear method.
