Summary:

It is important to obtain durability loads at early design stage when no representative vehicle is available. Without road load data acquisition, durability loads have to be derived from mathematical modeling or approximation of spindle loads being acquired previously. Spindle load scaling by corner weight is a quick method for load estimation. No study has been found reporting statistical or theoretical relationship between corner weight and load. Current study presents the statistical relationship between corner weight and measured spindle load. Thirty-one sets of measured spindle load data are studied. These data sets include heavy duty trucks, SUV, minivan, family passenger cars, and small cars. The range of corner weight at left front wheel is between 5430 N and 12479 N. Considering all spindles, there is a strong statistical relationship between vertical spindle load and corner weight with R-square greater than 0.7; there is also a moderate statistical relationship between lateral spindle load and corner weight with R-square greater than 0.5; however, poor statistical relationship between fore/after spindle load and corner weight is found
