Kinematic Joint Recognition in CAD Constraint Systems
نویسنده
چکیده
We study the joint recognition problem, which asks for the identification and classification of kinematic joints from a geometric constraint system. By laying the foundation for a rigidity-theoretic study of flexible body-and-cad frameworks, we obtain an O(n) algorithm for identifying prismatic and revolute joints relative to a specific body and an O(n) algorithm for finding all pair-wise joints. For a specific subset of bodyand-cad frameworks, we present a combinatorial algorithm for identifying all pairs of bodies with prismatic joints in O(n) time.

Kinematic and Dynamic Analysis of Tripteron, an Over-constrained 3-DOF Translational Parallel Manipulator, Through Newton-Euler Approach
In this research, as the main contribution, a comprehensive study is carried out on the mathematical modeling and analysis of the inverse kinematics and dynamics of an over-constraint three translational degree-of-freedom parallel manipulator. Due to the inconsistency between the number of equations and unknowns, the problem of obtaining the constraint forces and torques of an over-constraint m...

A numerical variational method is herein introduced for the automatic redesign of mechanical parts subject to a design change. This method is demonstrated to the design of mechanical parts in the context of concurrent engineering of 3D parts. Relations between dimensions in a mechanical part as dictated by a designer are modeled using mechanisms and their kinematic relations. Variational cut-jo...

متن کاملUser Interaction with Cad Models with Nonholonomic Parametric Surface Constraints
User manipulation of assembly models can provide insight during the early, formulative design stages into kinematic and dynamic characteristics of a mechanism. We present the advantages of kinematic representation of constraint equations in fully Cartesian coordinates, a departure from standard practice for interactive mechanical assembly at interactive rates. Formulations of a surface rolling ...
