<b>Vibration Analysis on Car Steering Due to Smooth and Rough Road Condition</b> In this project actually we are going to find out the vibrational analysis for different car steering for different road profiles. And also our aim is to find out or collecting out the vibrational values, to know the vibration of the steering in different road conditions. In this project we have used the accelerometer sensor for finding out the steering vibrational values in different road profiles. And also we have used the digital to analog converter, which convert the sensor reading values to the analog values.The methodology we have used as usually normal method to taking vibrational values of normal steering and power steering in smooth and rough road conditions. The values we have collected from the sensor readings are put it in the DEWE software for analyzing, in this software can find out which steering will produce more vibration in different road profiles. In this project we are going to find which steering will produce more vibration in different road conditions.
