摘要
根据推导的任意动力荷载作用下的弹性结构体系的动力稳定性判别准则，对一存在内共振的桅杆结构进行了算例分析，从对实际桅杆结构的动力稳定性分析中可以得知，桅杆结构的内共振是导致其动力失稳的主要因素之一。
An analysis of calculation example of a mast structure with internal resonance is conducted according to the derived criterion of the dynamic stability of an elastic structural system under random dynamic loads. It is known from the dynamic stability analysis of a real mast structure that this internal resonance of the mast structure is one of the major factors leading to its dynamic instability.
