A Computer Algorithm to Design Compound Gear Trains for Arbitrary Ratio
(The American Society of Mechanical Engineers (ASME), 1971)A novel numerical method to determine the numbers of teeth in the driver and driven gears in a compound gear train is presented as an algorithm for computer-aided design applications. A brief ... -
Contributions to the Determination of the Equations of Motion for Multidegree of Freedom Systems
(The American Society of Mechanical Engineers (ASME), 1971)This paper is a further development of the kinematic problem presented in our 1967 paper [1] in which we have obtained the transmission functions for different orders of plane systems with ... -
Six-Bar Cognates of Watt’s Form
(The American Society of Mechanical Engineers (ASME), 1971)The paper describes the equivalent of Roberts’ law for Watt-1 mechanisms. It is shown that two floating links of the mechanism may be in turn generated by more than one mechanism of this ... -
An Application of Boolean Algebra to the Motion of Epicyclic Drives
(The American Society of Mechanical Engineers (ASME), 1971)The kinematic structure of epicyclic drives has been investigated with the aid of Boolean algebra. The correspondence between the graph representation of the structure, the mechanism, and the ... -
Minimum Error Synthesis of Space Mechanisms for the Generation of Constrained and Unconstrained Screws
(The American Society of Mechanical Engineers (ASME), 1971)The RSRC space mechanism is synthesized to generate constrained and unconstrained screws of the form ψ̂(θ) = ψ0 (θ) + εψ1 (θ), where θ is the input parameter. A variational principle is used ... -
Synthesis of a Geared N-Bar Linkage
(The American Society of Mechanical Engineers (ASME), 1971)For certain tasks, four-bar linkages may not provide needed accuracy and/or structural characteristics. To overcome this, one or more bars may be added to the coupler with geared pairs to ... -
An Iterative Method for Analyzing Oscillating Cam Follower Motion
(The American Society of Mechanical Engineers (ASME), 1971)This paper describes a method of analyzing the kinematic characteristics of cams, with profiles represented by an eight-term Fourier series and with oscillating-type followers. Two kinds of cam ... -
Degrees of Freedom of Motion in Mechanisms
(The American Society of Mechanical Engineers (ASME), 1971)The general form of the mobility equation is presented, which predicts the number of inputs required to drive a multiloop mechanism having redundant freedoms, passive freedoms, different general ... -
Generalized Cycloidal Motion
(The American Society of Mechanical Engineers (ASME), 1971)The motion coefficients and design methods for a wheel rolling externally or internally to a fixed wheel are given in Part I for linkage constraint satisfying up to 6 multiply separated ... -
Mobility Analysis of Plane and Spatial Mechanisms
(The American Society of Mechanical Engineers (ASME), 1971)A geometric method for the investigation of the mobility of plane and spatial mechanisms is presented. The mobility conditions are determined explicitly and displayed in the form of mobility charts. -
Minimization of Mechanism Oscillations Through Flywheel Tuning
(The American Society of Mechanical Engineers (ASME), 1971)The magnitude of the perturbations to the steady-state rotation of most mechanisms is difficult to control with present methods. This paper shows an alternative method of reducing the magnitude ... -
A Relaxation and Gradient Combination Applied to the Computer Simulation of a Plane Four-Bar Chain
(The American Society of Mechanical Engineers (ASME), 1971)This optimization process uses only output data received from an analog simulation of the four-bar mechanism. The complexity of the analytical expression for the coupler curve is illustrated and ... -
A Generalized Symbolic Notation for Mechanisms
(The American Society of Mechanical Engineers (ASME), 1971)Revisions of the Denavit-Hartenberg symbolic notation are proposed which extend its use to the entire domain of rigid link mechanisms. The extended notation provides a clear separation of the ... -
