! TITLE: raceo_top_nhbb.parm (AAAV) ! !--------------------------------------------------------------------------- ! Rev - 03/26/2001 D. Edwards !--------------------------------------------------------------------------- ! ! This macro computes the equivalent thickness ring for a temperature test ! in an aluminum assembly. ! ! First the actual race deflection is computed with an arbitrary thickness ! aluminum sleeve assembled outside of the race. The race deflection at the ! ball contact points (use the minimum algebraic value) is used to find an ! equivalent uniform ring which compresses the same amount when assembled ! with the aluminum sleeve. ! !--------------------- a.)
