摘　　要：根据随机连续梁弯曲振动系统的固有频率与激振频率差的绝对值不超过规定值的关系准则,定义了随机连续梁弯曲振动系统的可靠性模式和系统的可靠度,提出了避免共振的频率可靠性分析方法,对随机连续系统共振问题的准失效分析方法进行了探索。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.
