The dynamic adsorption of Pb(II) ions from aqueous solutions using a granulated activated carbon and an activated carbon cloth has been studied using fixed bed adsorption column. The breakthrough curves at different hydraulic loading rates (HLR), bed depth and feed concentration (Co) have been examined. The breakthrough time at any given concentration of the effluent decreases with increasing h...
Water hydraulic fluid switching transmission (FST) has lower environmental load and lower energy loss in valves for using only ON/OFF valves. In addition, improvement of transmission efficiency can be expected by using accumulator as the second driving source and making use of waste energy by energy recovering action. This paper concerned with experimental results and a design of simulator of t...
The flexible control system for hydraulic pile hammer using main control valve is present to the requirement of rapidly reversing with high frequency. To ensure the working reliability of hydraulic pile hammer, the reversing performance of the main control valve should commutate robustness to various interfere factors. Through simulation model built in Simulink/Stateflow and experiment, the eff...
This paper presents a novel approach to the design of road adaptive active suspensions via a combination of linear parameter-varying control and nonlinear backstepping techniques. Two levels of adaptation are considered: the lower level control design shapes the nonlinear characteristics of the vehicle suspension as a function road conditions, while the higher level design involves adaptive swi...
To date, the assessment of technical level individual elements hydraulic drive systems has been significantly addressed, but most them were positive-displacement machines. Thus, development a criterion which takes into account maximum number indicators and devices is based on common methodological principles an important scientific task for machines, units, devices. Based systematic analysis ev...
Modern machine tools based on parallel kinematic architecture provide excellent performance in terms of stiffness/weight ratio. Also, hydraulic actuators are widely used in industrial applications due to several advantages like large force and torque, high power to weight ratio, rapid response. The current paper presents the mechatronic design of a translational 3-DOF parallel robot which uses ...
WinSRFR is an integrated software package for analyzing surface irrigation systems. Software functionalities and technical features are described in a companion article. This article documents an example application. The analyzed field is a graded basin (close-ended border) irrigation system. The event analysis tools of WinSRFR are used first to evaluate performance of the irrigation system and...
