a ir static pressure thrust bearing multip le gridmethod stiffness elastic pressure groove
A method of design ing a new bearing system is presented. The f inite difference computat ionmode l of the elastic membrane is established. The coup ling computat ion process is designed for the computat ion model o f the aerostatic bear ing w ith pressure groove and the finite d ifference computationmode l of the e lasticmembrane. The iterat ive process to so lve the fourth-order partial different ial equations ( e lastic m embrane deformed govern ing equat ion ) is exp lo red successfu lly w ith the mult-i g rid method. The experim enta l resu lts show: Thew idth and depth of annu larmembrane o f the bearing changesw ith the designed a ir pressure tom eet the control requ irements. The resu lts ind icate that the design, machin ing and test of the new structure are satisfacto ry and successful.
