An Experimental Investigation and Modal Analysis of an Engine Supporting Bracket

Engine supporting bracket playsa vital role in improving the ride comfort and work environments of the vehicle. It is anticipated that Improvement in vibration control can be achieved by the determination of natural frequency of engine supporting bracket system and must be less than self-excitation frequency range.This Paper describes higher stresses induced and its critical region on the component. In static structural analysis design is suggested against deformation, equivalent stress andstrain energy using finite element analysis concept. Existing design is modified and provided with the isolation effectsand on setstress distribution from critical region which concentrates on strengthened body part was suggested. Further scope of this work involves in carrying out vibration study using fast Fourier transform (FFT) analyzer

Design And Analysis Of Engine Mounting Bracket Using Ansys Tool

Engine mounting bracket plays very significant role in reducing noise, vibration and harshness caused due to engine and thus has very effective role in improving vehicle comfort. This current article accounts for the investigation of engine mounting bracket by using ANSYS. Static and modal analysis of engine mounting bracket was done in order to investigate whether the current natural frequency of engine mounting bracket is lower than that of self excitation frequency of bracket. The obtained results were also examined for cross section of bracket. It was found that circular cross section having stress induced 128.47MPa is more reliable than square cross section. The results were analyzed for stresses and deformations. The design was tested for different materials like Magnesium, ERW-1 and ERW-3 along with suitability of material. Stresses induced in magnesium bracket were 64.07 MPa with the deformation of 1.20 mm. It can be anticipated that magnesium brackets are corrosion resistant and can be considered for desired application
