Precise Lumped-Parameter Modeling of Flexible Manipulator Dynamics.

Modeling of a One Flexible Link Manipulator

Dynamics and control of flexible robot manipulators have received wider attention during the last two decades. In manufacturing and space applications, the use of lightweight structures in robot manipulators is motivated by their capacity for high speed maneuvers, their high payload to arm weight ratio, higher mobility, reduced energy consumption, and lower inertia forces for accurate positioni...

Dynamics of Flexible Manipulators

This paper presents an application of Continuum (i.e. Lagrangian) and Finite Element Techniques to flexible manipulator arms for derivation of the corresponding Dynamic Equations of Motion. Specifically a one-link flexible arm is considered for detailed analysis, and the results are extended for the case of a two - link flexible manipulator. Numerical examples are given for the case of both one...

Recursive Lagrangian dynamics of flexible manipulator arms via transformation matrices

Modeling of a Fully Flexible 3PRS Manipulator for Vibration Analysis

In this paper we provide a vibration analysis model and the modeling method for a fully flexible 3-Parallel-Revolute-joint-and-Spherical-joint (3PRS) manipulator—a sliding-leg tripod with flexible links and joints. A series of tripod configurations are set by rigid kinematics for simulation and experiment. All the links are modeled by finite elements: triangular membranes combined with bending ...

Dynamic modeling of structurally-flexible planar parallel manipulator

This paper presents a dynamic model of a planar parallel manipulator including structural flexibility of several linkages. The equations of motion are formulated using the Lagrangian equations of the first type and Lagrangian multipliers are introduced to represent the geometry of multiple closed loop chains. Then, an active damping approach using a PZT actuator is described to attenuate struct...
