Analysing of Sealing Properties on a Bolted Joint with a Steel Gasket by Using Finite Element Method

Abstract

This article deals with study of contact pressure/gap distribution on a bolted joint of a hydrostatic transmission. The study was performed via numerical analyses with support of ANSYS a finite element method software package. The main focus in the results evaluation is aimed on evaluation of the contact pressure/gap on the bolted joint after tightening individual bolts and after applying operational loads on the hydrostatic unit. Operational loads in the analyses were represented by applying of an operational pressure into the individual areas of the unit. The operational pressure was applied in two time steps of the Finite Element Method analysis to simulate normal and reverse mode of the hydrostatic transmission. Numerical results were verified through experimental measurements carried out by using FujiFilm tests.
