RISA Distribution Method of Driving Torque for a Novel 3UPS-RR Redundant Solar Tracker
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a novel two-axis solar tracker with a redundant parallel mechanism and investigates the distribution method of driving torque. In view of the difference between the singular configuration of the redundant ...
Approaches to Predicting the Vertical Transmissibility of a Suspension Seat With a Seated Subject
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, four methods were put forward to predict the transmissibility of an air suspension seat with a seated subject. For characterizing the dynamics of the suspension seat, two of the methods were based on developing ...
A Streamline-Guided Dehomogenization Approach for Structural Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a novel dehomogenization approach for the efficient design of high-resolution load-bearing structures. The proposed approach builds upon a streamline-based parametrization of the design domain, using a set of ...
A Control Strategy of a Two Degrees of Freedom Heavy Duty Parallel Manipulator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The motion accuracy of a heavy duty parallel manipulator is usually low due to time lag and the difficulty to realtime measure the position of the endeffector. In this paper, a dynamic modeling of this system with consideration ...
A Measure for Evaluation of Maximum Acceleration of Redundant and Nonredundant Parallel Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper deals with the evaluation of acceleration of redundant and nonredundant parallel manipulators. The dynamic model of three degreesoffreedom (3DOF) parallel manipulator is derived by using the virtual work principle. ...
A Fourier Descriptor-Based Approach to Design Space Decomposition for Planar Motion Approximation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an earlier work, we have combined a curve fitting scheme with a type of shape descriptor, Fourier descriptor (FD), to develop a unified method to the synthesis of planar four-bar linkages for generation of both open and ...
Transient Analysis of a Flexible Pin-on-Disk System and Its Application to the Research Into Time-Varying Squeal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a flexible pin-on-disk system is used to simulate how squeal noise can be generated in frictional contact. As the research object, the modeling process and transient simulation method of the flexible pin-on-disk ...
Torque Optimization Method of a 3-DOF Redundant Parallel Manipulator Based on Actuator Torque Range
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The small actuator torque range brings advantages for the high-accuracy control of a manipulator. By taking the minimum actuator torque range into account, this paper proposes a novel torque optimization method of a 3-DOF ...
Kinematic Acquisition of Geometric Constraints for Task Oriented Design of Planar Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A motion task can be given in various ways. It may be defined parametrically or discretely in terms of an ordered sequence of displacements or in geometric means. This paper studies a new type of motion analysis problem ...
Treatment of Leachate by Aged-Refuse-based Biofilter
Publisher: American Society of Civil Engineers
Abstract: Refuse in landfills becomes stabilized or aged, as organic matter in the refuse gradually degrades and as the soluble inorganic substances dissolve during its long-term stabilization process. Within this paper, this process ...
