Flow Characteristics and Sizing of Annular Seat Valves for Digital Displacement Machines

Design and Modelling of Fast Switching Efficient Seat Valves for Digital Displacement Pumps

Digital Displacement Fluid Power Pumps/Motors are promising candidates for revolutionizing the efficiency of fluid power systems, which traditionally has suffered from poor efficiencies, especially at part load. The key to obtain efficient part load operation with digital displacement technology lies in the development of very fast switching seat valves with a corresponding low pressure loss. T...

Aortic Valve Annular Sizing

Sizing up the soul’s seat

In search of a reptilian cortex: With evidence in hand that birds may have a cortex-like structure in their brains, the search is now on to explore brains in a wider array of vertebrates, particularly reptiles which are closely related. Sea turtles are known for their navigational abilities, crossing huge distances in the open ocean to reach a preferred beach for egg laying. It’s possible that ...

Moditication Factor for Sizing Equation of Electrical Machines-Single and Three Phase Induction Motors(RESEARCH NOTE)

Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...

Vibration characteristics of tractor seat cushion materials

Operators of agricultural machinery are exposed to an extensive range of indirect vibrations through the seats, which gradually causes chronic damages. One of the ways to reduce the vibrations imposed on the operators is to use appropriate materials in tractor seat cushion. The present study was carried out in order to select appropriate foam or sponge and investigate different factors in reduc...
