A Tire Model for Off-Highway Vehicle Simulation on Short Wave Irregular Terrain

Manufacturers of construction machinery are challenged in several ways concerning dynamic loads. Considering off-highway dump trucks that travel through high amplitude short wave irregular terrain with considerable speed two aspects concerning dynamics are important.The first is the legal requirements that prescribe the maximum limit on the vibration exposure on the operator which is a measure for ride comfort.The second is the importance of knowing the dynamic loading of the structural parts. In order to use the wide variety of computer-aided design tools to size and optimize mechanical joints, spring-damper elements and the welded structures it is crucial to have information on the time h…
