Random Vibration Analysis for Starter Motor of Three Wheeler Automobile

“

Automobile industries have prime importance to vibration testing. Sine vibration testing is performed when we have been given with only one frequency at given time instant. Trend to perform random vibration testing has been increased in recent times. As random vibration takes into account all excited frequencies in defined spectrum at known interval of time, it gives real-time data of vibration severities. The vibration severity is expressed in terms of Power Spectral Density (PSD). The consideration in the paper is based on the fact that we will be dealing with only random vibration. Aim of paper is to perform random vibration analysis for starter motor mounted on an engine and also find its transmissibility value.
