PRESSURE ACCUMULATOR DISCHARGE EFFECT ON GEAR SHIFT WITH HYDRAULIC CONTROL BOX

Effect of Cyclic Hydraulic Pressure on Osteocytes

INTRODUCTION: Although bone is known to respond to various forms of mechanical loading including substrate strain, fluid shear, and interstitial fluid pressure, the latter receives relatively little attention. . Macroscopically, venous stasis or applied pressurization by external loading was associated with increased bone formation.. At the cellular level, osteoblasts have been shown to respond...

Effect of pressure on aortic hydraulic conductance.

This study was performed to determine whether the transmural hydraulic conductance (Lp) of the rabbit aortic wall depends on its distension. In 19 rabbits, the aorta was cannulated in situ and perfused at a given pressure with a physiologically buffered solution containing 4% bovine serum albumin. The output cannula was then occluded to limit fluid flow to that traversing the artery wall. Exter...

Mathematical Modelling of a Hydraulic Accumulator for Hydraulic Hybrid Drives

Simultaneous Optimization of Supervisory Control and Gear Shift Logic for a Parallel Hydraulic Hybrid Refuse Truck Using Stochastic Dynamic Programming

The power management controller of a hybrid vehicle orchestrates the operation of onboard energy sources, namely engine and auxiliary power source with the goal of maximizing performance objectives such as the fuel economy. The paper focuses on optimization of the power management strategy of the refuse truck with parallel hydraulic hybrid powertrain. The high power density of hydraulic compone...

Effect of Hydraulic Accumulator on the System Parameters of an Open Loop Transmission System

This paper denouements the study of operating parameters of a hydraulic transmission system with and without the application of hydraulic accumulator. In this respect, the hydraulic system, designed in the open circuit mode, consists of the fixed displacement hydraulic pump which gives pressured fluid to the hydro-motor and charges the accumulator as well. The load on the motor is controlled hy...
