Hydraulic bending roll system has become one of key equipments to control the exit strip shape in strip rolling mills. The hydraulic bending roll system of a hot rolling mill was researched and analyzed, and its mathematics models were founded in whole based on the action principle of some representative hydraulic components. At last, the hydraulic bending roll system was simulated with MATLAB ...

The speed and torque of the hydraulic motor is controlled by controlling the hydraulic valve pump connected to the hydraulic motor. An electro hydraulic valve coupled to a hydraulic motor is a common method of motor speed control in practice where both load pressure and speed change during operation. In this paper, system equations that include, flow and toque loss term has been established by ...

This paper describes the implementation of a real-time hydraulic model of a water distribution system in Singapore. This on-line system is based on the Integration of real-time hydraulic data with hydraulic computer simulation models and statistical prediction tools. To facilitate this implementation, a network of wireless sensor nodes continuously sample hydraulic data such as pressure and flo...

1 Hans Kleine Büning, Benno Stein ABSTRACT Configuration is a process of creating complex systems out of a finite set of predefined objects. This process may enclose the selection, the assemblage and the adaptation of these objects. In this paper we want to describe how the configuration of hydraulic plants can be supported. A hydraulic plant is a complex system that consists of electronic, mec...

Hydraulic systems are widely used in industry because of the advantages of their small size-to-power ratios and their ability to produce very large linear force and torque. There are tendencies for compact electro-hydraulic systems which deliver powerful, linear movement having hydraulic oil circulation only when operating. This paper investigates directly driven hydraulic setup for non-road mo...

The function diagram of active heave compensation hydraulic system has been given, besides, the mathematics model for the principal hydraulic components of the compensation system has been built, and the input-output relation between components has been made clear. Aimed at compensating work capacity for the system, design and research on parameters as the bearing pressure, the initial state an...

Electro hydraulic drives are often used where the dynamic response requirements of the driven load in terms of speed, cycling, accuracy and stability are particularly severe. One such application is the control and drive system associated with a high frequency hydraulic vibrator. A hydraulic shaker controls a valve which directs high pressure hydraulic fluid to generate controlled vibration. Hy...

We are studying a hydraulic system design and vehicle dynamic modeling for a development of tire roller system, because those are very important in analysis of tire roller. Generally, tire roller is one of the useful machines in a road construction field and it technically applied for many other construction fields. Also, we conceptualize of new hydraulic and traction system, and define about t...

Hybrid electric vehicles employ a hydraulic braking system and a regenerative braking system together to provide enhanced braking performance and energy regeneration. In this paper an integrated braking system is proposed for an electric hybrid vehicle that include a hydraulic braking system and a regenerative braking system which is functionally connected to an electric traction motor. In the ...
