Zero Voltage Switching Converters (140939)


Abstract : Contact is the principal method of applying loads between deformable solids,and therefore is present in a wide variety of mechanical components. In addition,contacts usually act as stress concentrations,and are thus probable locations for mechanical failure. Some of the most typical mechanical failures involving contact include:fretting,fretting fatigue,wear,fret ting wear and false brinelling. The contact of UIC - 60 and IRS - T12 rail - wheel has been analyzed by hand calculations to determine contact stresses. A three dimen sional finite element model of both type of rail - wheel contact is developed in ANSYS to compare to the typical hand - calculated s tresses. A vertical force is applied railway wheel & simulates the effects frictional surfaces. The results of the finite element model analysis contained herein are compared to hand calculations. Based on these results,a finite element analysis should be used if a greater level of detail is required for the analysis of the rail - wheel contact.
