The Vehicle-Terrain Interface (VTI) model for off-road vehicle performance is often used in virtual prototyping to support preliminary vehicle design.
The stochastic tire snow models developed are based on the extension of two representative deterministic tire snow interaction models developed at the University of Alaska, including the pressure stress deterministic model and the hybrid (on-road extended for off-road) deterministic model.
Comparison of the predicted versus measured performance parameters suggests that the closed form solutions within the VTI model are functional but can be further improved to provide more accurate predictions for off-road vehicle performance.
Mr. Barnes said Freightliner did not plan to sell anywhere near that many Unimogs, because the company wants to establish a reputation for off-road performance that might suffer if smaller, less expensive models were introduced.
Increasing concerns on human driver comfort/health and emerging demands on suspension systems for off-road vehicles call for an effective and efficient off-road vehicle ride dynamics model.
Traditionally, the design of cooling systems for off-road machines has relied on steady-state and quasi steady-state cooling system models.
While there is still plenty of room for innovation in the wheelchair market, the Model Ci and other WHILL products compete with devices like the iBot, which can climb stairs, and the Trackchair, designed for off-road use.
The weight of MRAPs (with models ranging from 9 to 25 tons) and their top-heavy weight distribution make the vehicles prone to rollovers and less than ideal for off-road use.
That moniker traditionally was applied to road bikes that had been made off-road worthy, particularly for off-road competition.
However, emission standards for off-road vehicles and industrial applications are generally introduced after those for on-road vehicles and, therefore, many off-road applications were still largely uncontrolled in 2000.
Controlled traffic should be considered when developing management strategies for off-road driving in wildlife protected areas.
