Abstract
An engine mount is a structure that holds the engine to the chassis.The engine mounting plays significant role in
reducing the noise and vibrations for improving vehicle ride amenity. The Automobile engine chassis system may
experience unwanted vibrations caused by interference between the road and the engine. Engine bracket has been
designed as a structure to support engine. Due to vibrations of engine the holes on the engine Bracket get expanded
which leads to the failure of bracket. This paper presents experimental and Finite Element analysis of a typical
engine mounting bracket. In this paper we have explored usage of Modal Analysis in FEA to determine the
frequency band and check the bracket for safety. Hence in this paper, we have undertaken experimental analysis for
co-relation to establish variation of percentage and thus determine the nature of Boundary conditions to be used in
FEA for more accurate analysis. Experimental analysis is done by Fast Fourier Transform analyzer. Finite Element
analysis includes Static and Modal analysis using ANSYS15.0 which will determine natural frequency of engine
bracket.

1. Introduction
An engine mounting bracket is a component that supports the engine to the engine cradle of an automobile.
Purpose of mounting bracket is to damp engine vibrations and to stabilize as well as properly align engine. Common
indications of a failed engine bracket are the intense noise and vibration felt inside the car. When the engine runs,
bracket gets excited by forces caused by engine transmission. If any of the excitation frequency coincides with the
