Analysis of Sealing Properties on a Bolted Joint Based on Probability

Abstract:

This article deals with the study of the sealing properties on a bolted joint on a hydrostatic transmission. The main idea of this study is aimed at the probability assessment of fluid leakage due to the mechanics that play a significant role in the sealing properties. The study was performed via numerical analyses by using a FEM software package, ANSYS Workbench. The main focus when evaluating the results is aimed at the observation of the contact pressure and contact gap on the bolted joint. In this study two variables on the bolted joint, which can affect the sealing properties were taken into account, the torque applied through the bolts and the surface finish under the heads of the bolts.
