A novel elastoconstriction resistance relationship has been developed to aid in the rapid prediction of thermal resistance across spacecraft bearings. The development is based upon new definitions of effective contact curvatures and recently published approximations of the Hertz parameters. The elastoconstriction expression shows explicitly the influence of contact geometry upon the resistance. Differences between the approximate values and those predicted by the complex, exact Hertz equations are less than 1.7 % for all ball/race contacts encountered in spacecraft design. A typical example is cited to demonstrate the simplicity and accuracy of the new expression. (Kursetz)
