RISModeling and Analysis of Flow-Induced Vibrations in Circular Saws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two types of flow-induced vibrations in idling circular saws, random vibration and resonant vibration, were modeled and analyzed. The excitation source, which is the flow pressure fluctuations, ...
Optimal Trajectory Generation for Robotic Manipulators Using Dynamic Programming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of optimal control of robotic manipulators is dealt with in two stages: (1) optimal trajectory planning, which is performed off-line and results in the prescription of the position ...
Automated Symbolic Derivation of Dynamic Equations of Motion for Robotic Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general computer program for deriving the dynamic equations of motion for robotic manipulators using the symbolic language MACSYMA has been developed. The program, developed based on the ...
Application of Linear Assignment Model for Planning of Robotic Printed Circuit Board Assembly
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A planning method is presented for achieving shorter working-in-process and thus better productivity of printed circuit board assembly. This method finds the optimal sequence of component placement ...
Planning of Component Placement/Insertion Sequence and Feeder Setup in PCB Assembly Using Genetic Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new application of the genetic algorithm approach is introduced to solve printed circuit board assembly planning problems. The developed genetic algorithm finds the sequence of component ...
Vortex Shedding: The Source of Noise and Vibration in Idling Circular Saws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vortices separating from the edges of cutting teeth were shown to be the dominant source of pressure fluctuation and hence noise in circular saws. Measurement of pressure on the surfaces of ...
Feasible and Optimal Designs of Variable Air Gap Torque Motors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problems of automating the feasible and optimal designs of variable air gap torque motors are studied. Both are formulated as constrained optimization problems, where equality and inequality ...
Mating of Rigid Parts by a Manipulator With Its Own Compliance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In most assembly tasks involving mating of parts, industrial robots are not equipped with special compliant devices such as a remote center compliant hand. It is useful to know how the mating ...
Whistling Instability in Idling Circular Saws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Whistling is a self-excited transverse instability that produces intense noise at a resonant frequency of a circular saw. Experiments were undertaken to examine the noise source dependence upon ...
PDF Subvariable Control and Its Application to Robot Motion Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for determining the feedback coefficients of pseudo-derivative-feedback control is presented, along with applications of this control scheme. Simulations are performed for controlling a ...
