Summary:

Designing trucks for good ride characteristics is a challenge tothe engineer, given the many design constraints imposed byrequirements for transport productivity and efficiency. Theobjective of this lecture is to explain why trucks ride as they do,and the basic mechanisms involved.The response of primary interest is the vibration to which thedriver is exposed in the cab. Whole-body vibration tolerance curvesgive an indication of how those vibrations are perceived at theseat; however, ride studies have shown that visual and hand/footvibrations are also important to the perception of ride intrucks.The ride environment of the truck driver is the product of theapplied excitation and the response properties of the truck. Themajor excitation sources are road roughness, the rotatingtire/wheel assemblies, the driveline, and the engine. In thelow-frequency range the truck's response to these inputs ispredictable from rigid-body models of the basic suspensionisolation mechanisms, and the pitch-plane tuning to road inputscharacterized by "wheelbase filtering." At higherfrequencies, the response is influenced by frame bending, cabmounting, fifth wheel position, trailer loading, and othervariables. Examples of the influences on ride from these manyvariables are given
