Velocity Input

An experimental RSSR crank and rocker mechanism has been devised and manufactured to facilitate the dynamic investigation of the input and output torques present, the force components acting in the link members and at the joints of the machine under various loading conditions, for a number of different configurations. The behavior of the so-called redundant or passive degree of freedom is also investigated by means of a coupler (floating link) having its center of gravity offset from the center line of the spherical joints at its ends. Experimental observations are made for the constant torque and constant velocity input conditions, as obtained in a practical mechanism, for the various machine configurations and loading arrangements. An analytical model is developed using the classical Newton-Euler approach and an example of the correlation of the analytical and experimental results is given.

While record grooves have been studied by transmission electron microscopy with replica techniques, and by optical microscopy, the former are cumbersome and restricted and the latter limited by lack of depth of focus and resolution at higher magnification. With its great depth of focus and ease in specimen manipulation, the scanning electron microscope is admirably suited for record wear studies.A special RCA sweep frequency test record was used with both lateral and vertical modulation bands. The signal is a repetitive, constant-velocity sweep from 2 to 20 kHz having a duration and repetitive rate of approximately 0.1 sec. and a peak velocity of 5.5 cm/s.A series of different pickups and numbers of plays were used on vinyl records. One centimeter discs were then cut out, mounted and coated with 200 Å of gold to prevent charging during examination. Wear studies were made by taking micrographs of record grooves having 1, 10 and 50 plays with each stylus and comparing with typical “no-play” grooves. Fig. 1 shows unplayed grooves in a vinyl pressing with sweep-frequency modulation in the lateral mode.
