RISA Contribution to Gruebler’s Theory in the Number Synthesis of Plane Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple algorithm is introduced to solve Gruebler’s equation for constrained kinematic chains. Use of these criteria, however, brings clearly to the fore other problems, especially for mechanisms ...
Coefficient of Restitution Interpreted as Damping in Vibroimpact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During impact the relative motion of two bodies is often taken to be simply represented as half of a damped sine wave, according to the Kelvin-Voigt model. This is shown to be logically ...
The Intersections of Solids Shown by Electronic Analog for Mechanism Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The motion of certain spatial mechanisms with up to five links and containing at least one ball-and-socket joint can be visualized and analyzed by considering the intersections of three-dimensional ...
Multiple Impacts of a Ball Between Two Plates—Part 1: Some Experimental Observations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is a report on a series of physical experiments made with a steel sphere vibrating while trapped between and impinging against two end plates, as in an impact damping device, while ...
Digital Simulation of Impact Phenomenon in Spur Gear Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A digital simulation model is developed to represent a lightly loaded geared torsional system consisting of a drive unit, spur gear pair and load connected by flexible shafts. A clearance model ...
Structural Synthesis of a Four-Bit Binary Adding Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The structural permutation method (the “number” synthesis) of linkages is used to produce a collection of linkage forms with mobility 4. The steps of the procedure are carefully explained in ...
A Method of Numerical Evaluation of a Large Determinant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When solving problems in the vibration of a close-coupled system, there arises the need to expand a tridiagonal determinant of the type of equation (1). A very quick and accurate means of ...
Stereoscopic Drawings Made by Analog Computer of Three-Dimensional Surfaces Generated by Spatial Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spatial mechanisms with up to five links and containing at least one ball joint can be solved by considering the intersection of the three dimensional surfaces which can be generated by ...
Multiple Impacts of a Ball Between Two Plates—Part 2: Mathematical Modelling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model is developed to portray the vibroimpacts of a steel sphere which is trapped between two flat steel plates with clearance, while the plates are oscillated by an electromagnetic ...
Gross Motion Attributes of Certain Spatial Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method is presented by which positions of peculiar kinematic interest, such as ends of travel, locking positions and points of “uncertainty,” in certain types of spatial mechanisms can ...
