RISFlexibility Effects—Estimation of the Stiffness Matrix in the Dynamics of a Large Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an estimation of the stiffness matrix for a mechanical tree-like structure is presented. The coefficients of the stiffness matrix are evaluated based on Kane’s equations together ...
Dynamics of Large Constrained Flexible Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an automated procedure useful in the study of large constrained flexible structures, undergoing large specified motions. The structure is looked upon as a “partially open ...
Natural Dynamics of Robot Manipulators in the Presence of Obstacles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the natural dynamic control problem of robot manipulators and its application to collision avoidance and path planning. A set of moving convex obstacles (or polyhedron) are ...
Nonlinear Modeling of Flexible Multibody Systems Dynamics Subjected to Variable Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the geometric stiffening effects and the complete nonlinear interaction between elastic and rigid body motion in the study of constrained multibody dynamics. A recursive ...
On the Constraint Violations in the Dynamic Simulations of Multibody Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an automated and efficient mathematical model for checking the violations of the constraints in the dynamics of multibody systems. The superfluous generalized independent speeds ...
Coordinate Reduction in the Dynamics of Constrained Multibody Systems—A New Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper a new theorem for the generation of a basis for the null space of a rectangular matrix, with m linearly independent rows and n (n > m) columns is presented. The method ...
Analytical Method for the Analysis and Simulation of Human Locomotion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An all purpose computer algorithm used in the analysis and simulation of human locomotion is presented. The utility of the program “DYAMUS” stems from its simplicity in defining the initial ...
Optimization of the Contact Damping and Stiffness Coefficients to Minimize Human Body Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a lumped mass human model is used to minimize the energy absorption at the feet/hip level when the body is subjected to vertical vibration. The contact forces are assumed ...
Dynamic Analysis of Flexible Gear Trains/Transmissions: An Automated Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper an automated algorithmic method is presented for the dynamic analysis of geared trains/transmissions. These are treated as a system of interconnected flexible bodies. The procedure ...
A Recursive Householder Transformation for Complex Dynamical Systems With Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method is presented by which equations of motion of complex dynamical systems are reduced when subjected to some constraints. The method developed is used when the governing equations ...
