This paper introduces the actual operation situation of swift hydraulic pipeline and several energy dissipaters in the extended engineering of Tangjiawan Reservoir of Wutai County.

Under the hostile submarine conditions,the dynamic characteristics of a submarine fluid conveying pipeline in a suspended span is quiet different from those of a pipeline on land,which was affected by the coupling effect of the flows inside and outside the pipeline.

Stability of pipe conveying fluid under axial load;

Research on natural frequency of pinned-pinned pipe conveying fluid;

Based on the stress anylysis of element,the vibration differential equation of the pipe conveying fluid on elastic foundations is derived,the mode and the nature frequency of the pipe are calculaed by variable-separating method and numerical method.

An effective solution to dynamic response of pipes conveying fluid;

Internal resonance conditions of supported pipes conveying fluid

The parametric resonance of clamped-pinned pipes conveying fluid was investigated experimentally.

The differential quadrature method(DQM)is extended to solve the natural frequencies of pipe.

Very often when mechanical operation applied to piped flowing fluid, a state transform will occur as a result inducing a hydraulic transient, or even waterhammer when situation is severe.

Nonlinear dynamic characteristics of a fluid conveying pipe under condition of commonly elastic supports

Notch filter feedback control for chaotic motion of fluid conveying pipe

When a fluid conveying pipe fixed at two ends is excited by harmonic motion of the base and its chaotic motion occurs,the analytic conditions that its parameters should satisfy are studied by using Melnikov method.
