An approximate solution for the pressure distribution around a finite length, herringbone grooved journal bearing is derived in analytical form. Some results for the bearing stiffness and attitude angle are presented and compared with experimental results and other theories. The effect of changing the number of grooves is investigated. The validity of the approximate method used is checked by applying it to a simple step slider bearing for which exact solutions are available. The theoretical development is extended to cover the dynamic loading case. Theoretical solutions for the amplitudes of vibration for different frequencies are compared with experimental results.
