简述了随机结构动力学的发展历程,给出了日益复杂的随机结构动力学问题的解析方法,并以实例说明随机结构动力学在土木和航空工程中的应用。讨论了工程结构的各种随机损伤,包括运动失稳、首通问题和疲劳损伤。 The development process of stochastic structural dynamics is briefly described. An increasingly complicated analytical method of stochastic structural dynamics is given. An example is given to illustrate the application of stochastic structural dynamics in civil engineering and aeronautical engineering. Discusses a variety of random structural damage, including motion instability, first pass problems and fatigue damage.
