Design and Manufacturing of Pneumatic Based Vibration Exciter

Abstract

The test component or part under study is subjected to the mechanical vibratory motion. This motion is generated by the vibration exciter. Designing of such exciter machine along with its construction and performance testing is focused in this study. This machine has unbalanced mass which generates uniaxial vibrations. Specified range of harmonic or time dependent excitation force is generated by the exciter. Also, time dependent displacement through a specified frequency is achieved. The vibrations are generated due to centrifugal force of eccentric mass which rotates. The vibrations produced lie in the low frequency range. The construction of working device and its important parts are described here. This exciter is used for testing of welded parts, small mechanical part. The obtained experimental results are in line with theoretical results. In this project we used pneumatic cylinder for provides vibration to fixer plate and pneumatic cylinder will actuate with help of solenoid valve and microcontroller. testing specimen will be mounting on fixer platform Model analysis will be require find out natural frequency of test specimen and validates with the help of FFT analyser impact hammer test.
