Abstract
Many different studies have been performed to understand brake roughness, and in particular how brake rotor Disc Thickness Variation (DTV) is generated. The intent of this paper is to analytically explore through non- linear finite element modeling methods the effects of wheel joint variables on brake rotor mounted Lateral RunOut (LRO). The phenomenon of LRO is believed to be a primary contributor to DTV generation and resulting brake roughness. CAE analyses were conducted in non-linear contact mechanics in which real contacts between components exist. Various joint designs were simulated to compare rotor LRO and coning. Several parameters inherent to the design of wheel joints were varied and studied. A comparative approach was used to develop specific design recommendations for LRO reductions.
