Design and Validation of Holding Fixture for Auto-Rickshaw Silencer Based on FEM and FFT Analyzer

Abstract

Designing a vibration fixture for the testing of automobile components poses a significant challenge for engineers. With numerous tests conducted in recent years to determine operating frequencies and assess stress and failure in automobile parts due to vibration, the importance of vibration testing in industries cannot be overstated. This project focuses on the development, implementation, and testing of a holding fixture for the vibration testing of an autorickshaw silencer using FEA analysis. The modal analysis of the muffler fixture is conducted using ANSYS software, revealing a natural frequency of 654.4 Hz. Experimental modal analysis is performed using an impact hammer to provide excitation, and data is analyzed and validated using an FFT spectrum analyzer. The experiment is meticulously planned and executed using design of experiment techniques to ensure statistical significance in the results obtained.
