A study on the characteristics of externally pressurized air bearings

In this study the direct numerical method is applied to solve the perturbed Reynolds" equation. To solve it the perturbed dimensionless mass f low rate is used as the boundary condition under the inherently compensated restrictor. The dynamic characteristics of a rotor supported in the externally pressurized air bearings, such as stiffness and damping coefficients, are analyzed, and as a result...

Experimental and Numerical Study of Tension Bearing Capacity of Circular Skirted Foundations Resting on Sand Bed

Skirted foundations are an appropriate alternative to deep foundations in onshore and offshore structures, which have the ability to withstand uplift loads, are also easy to be installed. The tensile performance of skirted foundations on sand was studied by physical and numerical modeling. Laboratory tests were carried out on small-scale foundation models with peripheral skirts. Numerical model...
