• This paper deals with a finite element analysis of gas-lubricated herringbone groove journal bearings operating at high speeds. An efficient finite element procedure is specially devised to predict static and dynamic performance characteristics of highspeed gas herringbone groove journal bearings operating at large journal eccentricities. The novel procedure is founded on the Galerkin weighted residual method employing a new class of high-order shape functions, which are derived from an approximate solution to the non-linear Reynolds equation within an element. Numerical predictions of bearing load capacity, attitude angle and dynamic force coefficients show the behavior of gas grooved journal bearings at high operating speeds.
