It explains how to model a rigid-body system and how to analyze it, and it presents the most comprehensive collection of the best rigid-body dynamics algorithms to be found in a single source. Rigid Body Dynamics November 15, 2012 1 Non-inertial frames of reference So far we have formulated classical mechanics in inertial frames of reference, i.e., those vector bases in which Newton’s second law holds (we have also allowed general coordinates, in which the Euler-Lagrange equationshold). •Movement has two components: •Linear trajectory of a central point (“translation”).

Angular momentum of a rotating rigid body O r j z y x Y Z X XYZ: Fixed frame, xyz: Body frame Consider a rigid body composed of N particles with masses m 1, m 2, . to rigid body dynamics in 3D as described by Doran and Lasenby [2003]. •Movement has two components: •Linear trajectory of a central point (“translation”). It explains how to model a rigid-body system and how to analyze it, and it presents the most comprehensive collection of the best rigid-body dynamics algorithms to be found in a single source. A) are usually different B) are always the same C) depend on their position D) depend on their relative position 2. PDF. Rigid body dynamics. • collision and contact. This book provides an up-to-date overview of results in rigid body dynamics, including material concerned with the analysis of nonintegrability and chaotic behavior in various related problems. •#⃗is the center of rotation. If a rigid body is in translation only, the velocity at points A and B on the rigid body _____ . Problems Control is … The wealth of topics covered makes it a practical reference for researchers and graduate students in mathematics, physics and mechanics.

Problems Performance is important! •Relative distances between all points are invariantto rigid movement. Rigid body simulation Once we consider an object with spatial extent, particle system simulation is no longer sufficient. Rigid body dynamics. • Constrained system! Introduction. 3 Rigid-Body Kinematics •Objects as sets of points. •Relative rotation around the point (“rotation”). A general rigid body subjected to arbitrary forces in two dimensions is shown below. . •Distance vector $⃗=!−#⃗. Mechanical systems often contain complex assemblies of interconnected parts undergoing large overall motion: suspension assembles in ground vehicles, robotic manipulators in manufacturing processes and landing gear systems in aircraft, for example.
