摘要: In engineering and technology, it is often demanded that self-oscillation.be eliminated . 50 that the equipment or machinery may not be damaged. In this paper, a mathematical model for reducing vibration is given by the following equations:x1+φ(x1)+k1(x1-x2)=0,x2+cx1+k2(x2-x1)=0 (*)We have discussed how to choose suitable parameters c1, k1, k2 of equations (*), so as to make the zero solution to be of global stability. Several theorems on the global stability of the zero solution of equations (*)are also given.
