A Motion Synthesis Approach to Solving Alt-Burmester Problem by Exploiting Fourier Descriptor Relationship Between Path and Orientation Data

Autor: Shashank Sharma, Anurag Purwar, Q. Jeffrey Ge

Publikováno v: Journal of Mechanisms and Robotics. 11

This paper presents a generalized framework to solve m-pose, n-path-points mixed synthesis problems, known as the Alt-Burmester problems, using a task-driven motion synthesis approach. We aim to unify the path and motion synthesis problems into an ap

An Optimal Parametrization Scheme for Path Generation Using Fourier Descriptors for Four-Bar Mechanism Synthesis

Autor: Shashank Sharma, Q. Jeffrey Ge, Anurag Purwar

Publikováno v: Journal of Computing and Information Science in Engineering. 19

Fourier descriptor (FD)-based path synthesis algorithms for generation of planar four-bar mechanisms require assigning time parameter values to the given points along the path. An improper selection of time parameters leads to poor fitting of the giv

Optimal Non-Uniform Parametrization for Fourier Descriptor Based Path Synthesis of Four Bar Mechanisms

Autor: Shashank Sharma, Q. Jeffrey Ge, Anurag Purwar

Publikováno v: Volume 5A: 42nd Mechanisms and Robotics Conference.

Fourier descriptor based path synthesis algorithms rely on harmonic decomposition of four-bar loop closure equation to split the design space into smaller subsets. The core of the methodology depends on calculation and fitting of Fourier descriptors.

Relationship among input-force, payload, stiffness and displacement of a 3-DOF perpendicular parallel micro-manipulator

Autor: Feng Gao, Xianchao Zhao, Yi Yue, Q. Jeffrey Ge

Publikováno v: Mechanism and Machine Theory. 45:756-771

In this paper, a three translational degrees of freedom (DOF) complaint perpendicular parallel micro-manipulator (PPMM) with monolithic structure is presented. The PPMM is driven by three piezoelectric actuators, and its three actuating directions ar

Fine Tuning of Rational B-Spline Motions

Autor: Lakshmi N. Srinivasan, Q. Jeffrey Ge

Publikováno v: Journal of Mechanical Design. 120:46-51

This paper presents two algorithms for ne-tuning rational spatial motions suitable for Computer Aided Design. The rational motions are represented by rational B-spline curves in a projective dual three-space known as the Image Space of Spatial Kinema

Designing Dynamically Compensated and Robust Cam Profiles With Bernstein-Be´zier Harmonic Curves

Autor: Lakshmi N. Srinivasan, Q. Jeffrey Ge

Publikováno v: Journal of Mechanical Design. 120:40-45

This paper deals with the problem of designing dynamically compensated cam profiles to minimize residual vibrations in high-speed cam-follower systems. The traditional Polydyne method is modified and extended to achieve significant improvement in res
