Eng. , 1993, 27: 119 125The Vibration of the Ball Guide with Linear MotionZhou Chuanhong Sun JianliAbstract The Static equations for force equilibrium of a ball guide system with linear motion and aset of dynamic differential equations are derived. The latter is solved by the 4 th order Runge-Kuttamethod, and the FFT software package is then used to process the results obtained. Various factorsaffecting the vibration of the ball guideare discussed. Calculated results are verified by tests.Key words: ba
