| 摘要： | Report developed under SBIR contract for topic A12-069. This project aims at addressing and remedying the serious limitations of the three-decade old multibody system (MBS) software technology currently used in the analysis, design, virtual prototyping, and performance evaluation of modern vehicle systems. These limitations are well known and are documented in the literature. The analysis of modern vehicle systems requires the development of complex models that include significant details that cannot be captured or accurately simulated using existing MBS codes which are based on rigid body assumptions or small deformation finite element (FE) formulations that are not suited for efficient communications with CAD systems. It is the main objective of phase I of this SBIR project to demonstrate the feasibility of developing a new MBS software technology that is based on new concepts and algorithms that can be used for accurate and efficient simulation of military and civilian wheeled and tracked vehicle models that include significant details. |
