LABORATORY STATIC TESTS ON BODY BOLSTER CENTER PLATES
Service experience has shown that the AAR standard separable body centerplates (both cast and forged) fabricated with a 3/4-inch thick flange and a 3/8-inch radius, between the bowl and flange, develop fatigue cracks around the bowl the 3/8-inch radius. The purpose of this test was to determine the stress reduction achieved by substitution of a 3/4-inch thick flange. Results showed the larger 3/4-inch radius reduced the stress in the area of failure. The lack of consistency in flange flatness influenced all results and masked the effect of the thicker 1-inch flange.
