On the Spherical Oscillating Cylinder Mechanism
(The American Society of Mechanical Engineers (ASME), 1969)If a plane oscillating cylinder mechanism is in the position where the slider and the crank are aligned, it has a Ball point on the slider. This Ball point coincides with the inflexion-pole. ... -
Generalized Cardan Motion
(The American Society of Mechanical Engineers (ASME), 1969)Cardan motion has been treated in the literature principally in terms of infinitesimally separated positions. Here Cardan motion is synthesized for all combinations of up to five infinitesimally ... -
On the Duality in the Existence of R-R Links for Three Positions
(The American Society of Mechanical Engineers (ASME), 1969)The present paper intends to report a discovery of geometric invariant in finite synthesis of space mechanism called “the duality of R-R link.” The duality itself is first proven here by using ... -
Roberts’ Cognates of Space Four-Bar Mechanisms With Two General Constraints
(The American Society of Mechanical Engineers (ASME), 1969)Thirty space, four-link mechanisms with two general constraints are investigated to study the existence of their coupler-curve cognates (Roberts’ cognates). The present study shows that the ... -
On a General Method of Spatial Kinematic Synthesis by Means of a Stretch-Rotation Tensor
(The American Society of Mechanical Engineers (ASME), 1969)One of the key concepts in a general method of spatial kinematic synthesis is a stretch-rotation operator applied to members of a general spatial kinematic chain. The latter consists of one ... -
Spatial Motions I—Point Paths of Mechanisms With Four or Fewer Links
(The American Society of Mechanical Engineers (ASME), 1969)Algebraic, geometric and some kinematic properties are derived for the paths generated by points on representative single degree-of-freedom spatial motions of four and fewer members. The motions ... -
On the Balancing of the Fluctuating Input Torques Caused by Inertia Forces in the Crank-and-Rocker Mechanisms
(The American Society of Mechanical Engineers (ASME), 1969)Some methods have been investigated both theoretically and experimentally to reduce the fluctuating torques in the driving shafts caused by the inertia forces in the crank-and-rocker mechanisms; ... -
Bicycloidal Crank—A New Four-Link Mechanism
(The American Society of Mechanical Engineers (ASME), 1969)Cycloidpoints were recently introduced [1]. The present paper demonstrates the existence of Burmester point trios at which the rotation of the moving plane between precision positions is a ... -
Gross Motion Attributes of Certain Spatial Mechanisms
(The American Society of Mechanical Engineers (ASME), 1969)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 ... -
Optimization of Four-Bar Linkages Satisfying Four Generalized Coplanar Positions
(The American Society of Mechanical Engineers (ASME), 1969)The optimal design of crank and rocker mechanisms satisfying four prescribed multiply separated positions of the moving plane is considered. The constraints are obtained from pairs of corresponding ... -
Calculation and Construction of the Burmester Points for Five Positions of a Moving Plane
(The American Society of Mechanical Engineers (ASME), 1969)A new method has been developed to derive the 10 Hackmüller conics going through the four Burmester points of five positions of a moving plane, and each going through another virtual center ... -
Coordination of Coupler-Point Positions and Crank Rotations in Connection With Roberts’ Configuration
(The American Society of Mechanical Engineers (ASME), 1969)In this paper a geometrical solution is given to the problem of finding four-bar linkages having 5 given coupler-point positions coordinated with 4 given crank angles. It may also be possible ... -
An Analytical Method for Synthesizing the Four-Bar Crank-Rocker Mechanism
(The American Society of Mechanical Engineers (ASME), 1969)An algebraic method is presented for synthesizing the four-bar crank-rocker mechanisms in general, with the offset slider-crank mechanism as a special case, for coordinating the prescribed input ... -
Inverted Slider Crank, Coupled in Tandem to Another Four Bar, to Generate a Constant Velocity Ratio
(The American Society of Mechanical Engineers (ASME), 1969)Combinations of the inverted slider-crank linkage (i.e., the Whitworth quick-return mechanism) with another of the same sort, with a scotch-yoke mechanism or with a planetary gear, are able to ... -
Complex Harmonic Analysis of Plane Mechanisms. Programming on Digital Computers and Experimental Examples
(The American Society of Mechanical Engineers (ASME), 1969)This article examines the plane hinged mechanisms with the aid of two original methods, i.e., a theoretical method and an experimental one. Each of these methods is based on the fact that ... -
A New Method for Completely Force Balancing Simple Linkages
(The American Society of Mechanical Engineers (ASME), 1969)A new method, herein referred to as the “Method of Linearly Independent Vectors,” is shown to permit the complete force balancing of certain planar linkages. This method consists of writing ... -
Solar Array Performance as a Function of Orbital Parameters and Spacecraft Attitude
(The American Society of Mechanical Engineers (ASME), 1969)The dependence of solar array energy on orbital parameters is given for cases that achieve optimum array pointing, and therefore, maximum performance. Optimum pointing requires continual array ... -
Discussion: “Stress-Concentration Factors in Shouldered Shafts Subjects to Combinations of Flexure and Torsion” (Rylander, H. G., daRocha, P. M. A., Kreisle, L. F., and Vaughn, G. J., 1968, ASME J. Eng. Ind., 90, pp. 301–308)

Problems of High-Speed Hydrodynamics
(The American Society of Mechanical Engineers (ASME), 1969)A hard look at the problems provoked by the quest for higher speeds of underwater craft shows that they can indeed be solved in a practical manner using the knowledge and principles derived ... -
