Dynamic Response of Suspended Pipeline under Excited Vibration of Supports

The little displacement of supports can induce vibration of suspended pipeline. In this paper, the fixing coefficient is used to simulate the restraints of adjoining spans, then single-span and multi-spans suspended pipeline can be regarded as single-span beam. Based on the simplified differential equation of excited vibration of Euler-Bernoulli beam, the dynamic response of suspended pipeline with common retraints under displacement of supports has been analyzed.
