RISReview of Contemporary Approaches for Constraint Enforcement in Multibody Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hallmark of multibody dynamics is that most formulations involve a number of constraints. Typically, when redundant generalized coordinates are used, equations of motion are simpler to derive ...
Tensorial Parameterization of Rotation and Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The parameterizations of rotation and motion are the subject of continuous research and development in many theoretical and applied fields of mechanics such as rigid body, structural, and multibody ...
Review of Classical Approaches for Constraint Enforcement in Multibody Systems
Publisher: The American Society of Mechanical Engineers (ASME)
