Analysis of Nonlinear Dynamic Model of Ball Bearing with Effect of Internal Radial Clearance
Abstract: It is a critical process to determine the response of rolling element bearing vibration using dynamic behavior analysis. Rolling element bearing works on the principal of transmission of load from moving race to stationary race. Generally outer race is fixed and load transmission takes place from inner race to outer race. In rolling bearing analytical formulation, the contact between rolling element and raceways is considered as nonlinear springs and their …

Experimental Investigation of a Supersonic Wind Tunnel under Different Operating Conditions
Abstract: This paper mainly describes the analysis and design of supersonic wind tunnel in order to reduce the power consumption using optimization techniques under to different operating conditions. In this analysis, a three-dimensional Navier–Stokes equation is used to investigate the flow field of a high pressure ratio centrifugal compressor for Supersonic Wind Tunnel. Such a compressor consists of a double-splitter impeller followed by a vaned diffuser. Particular attention is focused on …

Modal Analysis of Engine-mounting Bracket Using FEA for Circular Cross Section
Abstract: The engine mounting plays an important role in reducing the noise, vibrations and harshness for improving vehicle ride comfort. The first and the foremost function of an engine mounting bracket is to properly balance (mount ) the power pack (engine and transmission) on the vehicle chassis for good motion control as well as good isolation. The present work deals with finite element method (FEA) analysis of an engine mounting bracket. …
