TRUCK FRAME SIDERAIL DESIGN

The recent development of high strength steels for truck frame usage has led to a refinement of the section proportions of conventional channel siderail designs. To enable the frame designer to fully utilize the availability of high strength steels, to reduce the weight of truck frames and increase their durability, new design criteria must be established.

This paper highlights the basic design alternatives from which the frame designer can design improved frame assemblies utilizing high strength steels.
