Vehicle Dynamic Modeling and Simulation: Comparing a Finite-Element Solution to a Multi-Body Dynamic Solution.

摘要

Army needs high-fidelity multibody dynamic modeling of wheeled and tracked vehicles for predicting: Stability (going over a rough terrain at high- speed, lane change, etc.) Mobility analysis (going over bumps and potholes). Fatigue life and durability of various vehicle components. Two modeling and simulation approaches: Traditional solution: Rigid/Flexible Multibody Dynamics (MBD) codes. Alternate solution: Explicit Finite Element (FE) codes.
