Application of Variable Depth Siderail to Heavy Truck Frames

The heavy truck frame design engineer is faced with many factors when selecting a frame siderail. These factors must be weighed if the siderail is for one truck for a special application, or for a family of frames for tens of thousands of trucks involving the entire spectrum of heavy truck usage.

In this paper the various parameters of side bar selection are explored, and a lighter, less expensive design presented for higher gvw siderail applications.
