A method for finding the optimum distribution of slit density in a shoe upper, such that contact pressure with foot approaches an ideal is presented this paper. In upper made warp knitting, slits are by discontinuously knitting weft under uniform arrangement fiber. study, modeled as orthotropic hyperelastic body which defined design variable controlling intermediate maximum and minimum densitie...

In this study, an optimization methodology is presented to systematically define head-cutter geometry and machine tool settings to introduce optimal tooth modifications in spiral bevel and hypoid gears. The goal of the optimization is to simultaneously minimize the tooth contact pressure and the angular displacement error of the driven gear (the transmission error), to maximize the elastohydrod...

abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...

STUDY DESIGN The seat and back contact force, pressure distribution, lumbar lordosis, and low back muscle activities associated with a new seat design with adjustable ischial support and backrest were investigated using kinematic, kinetic, electromyographic, and radiographic measurements. OBJECTIVES To investigate the biomechanical effects of adjusting ischial and backrest supports during sit...

In order to analyze the temperature distribution of circuit breaker tulip contact, a thermal field simulation model for contact is built combined with electromagnetic-stress-thermal coupled finite element and virtual material method which models resistance characteristics contact. The rise characteristic contacts under rated current conditions short-circuit analyzed model. Results show that can...

An analytical equation of state is applied to calculate the thermodynamic properties for argon. Theequation of state is that of Song and Mason. It is based on a statistical-mechanical perturbation theory ofhard convex bodies and can be written as fifth-order polynomial in the density. There exist three temperaturedependentparameters: the second virial coefficient, an effective molecular volume,...

The aim of this study is to analyze foot pressure distribution of trail walking shoes while walking. Hiking, a recreational activity which is able to exercise whole body in the nature without any cost, has compositive effects which can reduce stress, strengthen muscles of entire body and improve cardiopulmonary function [1]. The Topography is hard near the surface and has rough characteristic b...
