Cause analysis of pipeline vibration in natural gas station [PDF]
Natural gas station is an important part of the whole natural gas pipeline transmission system, in which the pipeline vibration is a hidden danger that cannot be ignored for the safe operation of the station.

Gas hold-up in a three-phase reciprocating plate column [PDF]
The influence of the geometry of a reciprocating plate column (diameter), superficial gas velocity, vibration intensity and content of the solid phase in the column on the gas hold-up in a three phase column (G–L–S) were investigated in this study.

Modal analysis and harmonic response analysis of energy-absorbing and anti-scouring columns
Many field observations have found that damage to the support did not increase with the magnitude of the impact ground pressure. To enhance the impact protection performance of “support and surrounding rock” system. From the perspective of preventing the

Oxygen mass transfer in a 16.6 cm i. d. multiphase reciprocating plate column [PDF]
The effects of vibration intensity, superficial gas velocity and content of solid particles on the volumetric oxygen mass transfer coefficient (k1a) in a 16.6 cm i.d. multiphase reciprocating plate column were strudied.

Improving seismic resistance using absorbing nodes [PDF]
A flexible gusset is a device that improves the seismic resistance and energy dissipation capacity of a structure. To achieve these solo vibration characteristics, the flexible gusset is designed to remain elastic, resulting in reduced vibration to the ...

Vibration Damping in Bolted Friction Beam-Columns [PDF]
In this paper we consider dynamic friction within a bolted structure deliberately used to improve damping properties of engineering structures. The model considered for this paper consists of two steel beam-columns bolted together allowing dynamic friction to occur at the interface.

Interstitial gas effect on vibrated granular columns [PDF]
Vibrated granular materials have been intensively used to investigate particle segregation, convection, and heaping. We report on the behavior of a column of heavy grains bouncing on an oscillating solid surface. Measurements indicate that, for weak effects of the interstitial gas, the temporal variations of the pressure at the base of the column are ...

Simulation of Inhomogeneous Columns of Beads under Vertical Vibration [PDF]
We present results from computational experiments of one‐dimensional inhomogeneous granular column. With characteristic properties lying between those of liquids and solids, this class of material consists of assemblies of solid particles which interact via mechanical forces (contact and friction) and are maintained together by a gravitational field ...
