This paper covers the basic idea of using the test fixtures for vibration analysis and the effect of different
design variables on the dynamics of After-treatment system. Vibration Test Fixtures are the indispensable part in the
manufacturing industry. The vibration testing poses a challenge to design good vibration test fixture. Thus, to design the
fixture design guidelines; effect of design parameters are need to be studied. In present work, four cases are studied for
four different parameters. These parameters are material, fixing location, geometry and when fixture is replaced with
bracket. To study the effect of these parameters on the After-treatment system dynamics, we performed modal and PSD
analysis and compared the results with existing conditions.
