Abstract
Prediction of Design Margin for Diesel Exhaust Fluid Tank Bracket by FEA Approach - written by Sayali B. Pawar , Dr. Ranjit G.Todkar published on 2020/09/12 download full article with reference data and citations
Highlights
In mechanical engineering, a bracket is intermediate component for fixing one part to another
The fixture and bracket are made of aluminum and structural steel respectively
Diesel exhaust fluid tank is made of highdensity polyethylene rubber
Summary
The assembly consist of fixture, bracket and tank. FEA model of bracket is shown in fig. Fig (a) shows the FEA model of bracket in axial and lateral direction to obtain the frequency, acceleration and strain responses. Fig (b) shows the FEA model of bracket in vertical direction. The model is rotated because the gap between bracket and slip plate of shaker table in testing was less. To consider the actual testing condition, FEA model of bracket is rotated by 900 in simulation. Bracket and tank are meshed with quadrilateral element. The contact used between bracket and fixture for current model is bonded contact. Power spectral density analysis is used to determine the frequency, acceleration and strain responses. The input PSD profile is applied to the base plate of fixture.
