Deceleration control system for hydrostatic drive vehicles

Abstract: A combine harvester having a multiple-speed range mechanical transmission combined with a hydrostatic transmission and in providing valve means for the hydrostatic transmission which valve means is connected to the mechanical transmission so that pressure fluid is supplied to the hydrostatic transmission resulting in acceleration/deceleration of the harvester commensurate with the particular speed range selected.

Analysis of the Pressure Distribution for Press Shoe considering Partially Changed Curvature of Bearing Surface

Abstract: A press shoe is an element of a machine for squeezing water from wood pulp in the field of manufacturing paper. This is used to compress the pulp enveloped by felt sheet with a large roller. The squeezing force is made by hydraulic pressure. The press shoe has a mechanism similar to a partial hydrostatic bearing. The pressure profile between press shoe and roller affects their squeezing ability, and partial peak pressure can tear the wet pulp. The curvature of the surface of press shoe varies to reduce the peak pressure and increase the mean pressure simultaneously. Therefore, the prediction of pressure distribution considering partially changed curvature of hydrostatic bearing is very important for designing the press shoe. In this study, the difference formulation of Reynolds' equation for partial hydrostatic bearing is derived by direct numerical method and a computer program to calculate the pressure distribution is developed. We investigate the effect of partially changed curvature of bearing surface on the pressure distribution. Other design parameter for hydrostatic bearing such as depth of pocket and relative velocity are also studied.

Liquid Crystals and the Primitive Equations: An Approach by Maximal Regularity

Abstract: The two models we are considering in this work relate to the Navier-Stokes equations, which describe the motion of a viscous fluid. The first of these two models is the Beris–Edwards model of nematic liquid crystals, which couples the Navier-Stokes equations with a parabolic equation for the molecular orientation described by the Q-tensor. The second topic we are investigating is the primitive equations equations for atmospheric and oceanic flows, which are derived from the Navier–Stokes equations by the hydrostatic approximation.
