The use of finite elements to model soil/track interactions in coupled multi-body dynamic simulations: Is real time simulation feasible

PDF Version Also Available for Download.

Description

Finite element methods (FEM) employing the arbitrary Lagrangian-Eulerian (ALE) formulation may be used to model soil in contact with the wheels or the tracks of vehicles in off-road mobility simulations. Coupling ALE finite element methods with recursive multi-body dynamics may allow real-time simulation of vehicles off-road provided sufficient computational resources are available. The requirements of these approach will be discussed with emphasis on parallel implementation. Estimates of expected performance are calculated based on the current trend in the development of advanced computer architectures. Factors important in estimating the feasibility of using finite element methodology in real time will be considered. ... continued below

The requirements of these approach will be discussed with emphasis on parallel implementation. Estimates of expected performance are calculated based on the current trend in the development of advanced computer architectures. Factors important in estimating the feasibility of using finite element methodology in real time will be considered. Among these factors are the element size, the number of elements and the rate of computation, as well as the physical requirements of the simulations.
