中文摘要：
根据具有随机结构参数的转子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，定义了转子系统共振问题的可靠性模式和系统的可靠度，提出了避免转子系统发生共振的频率可靠性分析方法，根据失效准则，定义转子系统共振为串联系统问题，应用随机摄动技术、概率统计方法和可靠性理论，对具有随机结构参数的转子系统共振问题的准失效分析方法进行了探索和研究。
英文摘要：
Based on the relation criterion that the absolute value of frequency difference between the system and the excitation may not exceed a special value, the reliability mode and the safety probability of the rotor system with random parameters are defined. With the aid of the failure criterion, the resonance of rotor system is defined as series mode and the frequency relia- bility analysis method for avoiding the resonant is carried out. The quasi-failure analysis method for resonant problem of the rotor systems with random parameters is investigated by the random perturbation technique, probability statistics method and the reliability theory.
