RISMobility Analysis of Flexure Mechanisms via Screw Algebra
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a general framework for studying the mobility of flexure mechanisms with a serial, parallel or hybrid topology using the screw algebra. The current approach for mobility ...
A Pseudorigid-Body 3R Model for Determining Large Deflection of Cantilever Beams Subject to Tip Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a pseudorigid-body (PRB) 3R model, which consists of four rigid links joined by three revolute joints and three torsion springs, is proposed for approximating the deflection of ...
Realizing Orthogonal Motions With Wire Flexures Connected in Parallel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we study the type synthesis of wire flexures to achieve orthogonal motions by using a recently developed screw theory based design approach. For a given desired mobility pattern, ...
On Line Screw Systems and Their Application to Flexure Synthesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Motivated by the problem of synthesizing a pattern of flexures that provide a desired constrained motion, this paper presents a new screw theory that deals with “line screws” and “line screw ...
Complete Solution to the Eight-Point Path Generation of Slider-Crank Four-Bar Linkages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study the synthesis of a slider-crank four-bar linkage whose coupler point traces a set of predefined task points. We report that there are at most 558 slider-crank four-bars in cognate ...
Synthesis of Bistable Compliant Four-Bar Mechanisms Using Polynomial Homotopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we formulate and solve the synthesis equations for a compliant four-bar linkage with three specified equilibrium configurations in the plane. The kinematic synthesis equations as ...
A Polynomial Homotopy Formulation of the Inverse Static Analysis of Planar Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper formulates the inverse static analysis of planar compliant mechanisms in polynomial form. The goal is to find the equilibrium configurations of the system in response to a known ...
Development of a Dual-Handed Haptic Assembly System: SHARP
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Virtual reality (VR) technology holds promise as a virtual prototyping (VP) tool for mechanical assembly; however, several developmental challenges still need to be addressed before VP applications ...
Generalized Linear Product Homotopy Algorithms and the Computation of Reachable Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we apply a homotopy algorithm to the problem of finding points in a moving body that lie on specific algebraic surfaces for a given set of spatial configurations of the body. ...
Screw Theory Based Methodology for the Deterministic Type Synthesis of Flexure Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexure mechanism synthesis, however, is still a comparably difficult task. This paper aims at exploring a simple but systematic type synthesis methodology for general flexure mechanisms. The ...
