| Abstract: | The relation criterion of difference not beyond special value of the natural frequency and driving frequency is proposed.The reliability mode and the safety probability of the random bending vibration systems of bars are defined as series mode,and the frequency reliability analysis method for avoiding the resonant is carried out.The quasi-failure analysis method for resonant problem of the random bending vibration systems of bars is quested. |
