The Iltis all-terrain vehicle is used for military and civilian applications. Although the original design is from the 1970s, the Iltis is still in service in the Canadian army and the United Nations. The total vehicle weight is 1513.4 kg. The vehicle's suspension components are simple, and detailed data are available.
Benchmark results are available for a number of test cases .
The Iltis vehicle on a nonuniform road. The model also uses rigid bodies for suspension components, mass and rotary inertia elements to model the inertia effects, and user elements to model the interaction of the road and tires. Additional rigid elements and rigid surfaces are added to the model as display geometry for visualization purposes. In addition to the above components for modeling the mechanics, the model includes connector elements used as convenient measuring devices to record lateral acceleration, pitch angle, and roll angle. The tire model produces forces on the wheel hub due to linear stiffness in the radial direction, nonlinear lateral force and accompanying moment, and a self-aligning moment.
