New Linkage with Linear Actuator for Tracking PV Systems with Large Angular Stroke
solar tracking linkage linear actuator angular stroke transmission angle
2011/8/5
This paper focuses on the development of an optimized photovoltaic tracking system involving low-cost, relative simple mechanisms, with linear actuators able to insure strokes comparable with those re...
Pressure Control of a Large-scale Hydraulic Power Unit Using π Bridge Network
two stage pressure relief valve π bridge resistor network flow-pressure characteristics
2011/8/4
The steady state and dynamic characteristics of pressure output of a hydraulic power unit are important to the hydraulic system behavior. Because of the compact structure, the B-half bridge resistance...
Large unified symmetries of Emden dynamics systems
Large Unified Symmetry conserved quantity Emden dynamics system
2010/11/25
We propose a new concept of the Large Unified Symmetries and conserved quantities for Emden dynamics systems. We work on the Large Unified Symmetries and conserved quantities by the Noether symmetry, ...
Modeling and Verification of an Astronaut Handling Large-mass Payload
extravehicular activity inverse kinematics inverse recursive dynamics ADAMSTM
2011/8/3
The experiments on astronaut motions are difficult to conduct due to the limitation and high cost of constructing or simulating the microgravity environment of space. Therefore, the method of computer...
Modeling of Large Simple Shear Using a Viscoplastic Overstress Model and Classical Plasticity Model with Different Objective Stress Rates
Objective stress rates Classical plasticity models Viscoplasticity Simple shear
2009/10/12
Large simple shear deformation, which is usually used to test the applicability of various models, is studied by applying the classical plasticity model and the viscoplasticity theory based on overstr...
Diagnosis of Turbulence Radiation Interaction in Turbulent Flames and Implications for Modeling in Large Eddy Simulation
Turbulence-Radiation Interaction Large Eddy Simulation turbulent combustion radiative transfer
2009/10/9
An a priori study of the turbulence radiation interaction (TRI) is performed on numerical data from Direct Numerical Simulation (DNS) of a turbulent flame. The influence of the various correlations th...
Developing a Large Eddy Simulation Model (2DH FLOWER SD) for Flow Modeling in Compound Channels
Large eddy simulation Compound channel Turbulent flow Navier-Stokes equations
2009/9/30
As a compound channel is characterized by a deep main channel flanked by relatively shallow floodplains,the interaction between the faster fluid velocity in the main channel and the slower moving flow...
A Graphical Design of an Input-Shaping Controller for Quay-Side Container Cranes with Large Hoisting: Theory and Experiments
Input-shaping container crane crane control
2010/1/14
Input-shaping is a practical open-loop strategy for the control of transient and residual oscillations on cranes, especially those
having predefined payload transfer paths and repeated maneuvers. In ...
