Vehicle Vibrations Tire and Wheel Shakes

The wheel and tire vibration frequency is calculated by dividing the drive line frequency by the differential gear ratio. The differential gear ratio can be found in the ESM for the applicable vehicle model. If you can focus on a vibrating component (low frequency), the vibration is probably caused by wheels or tires.

Vibration Measurements: Vibration Analysis Basics

Vibration is an oscillating motion about equilibrium so most vibration analysis looks to determine the rate of that oscillation or the frequency, which is proportional to the system's stiffness. The number of times a complete motion cycle occurs during a period of one second is the vibration's frequency and is measured in hertz (Hz).

Creating a Vibration Transmissibility Plot

The plot below shows transmissibility for various damping ratios. Maximum transmissibility occurs at the natural frequency when undamped. As damping ratio increases, maximum transmissibility decreases and the maximum occurs at less than the natural frequency. For all damping ratios, transmissibility is 1, at f/fn = 2^.5 =

Vibration Measurement

Also, the amplifier should follow the bandwidth of the sensor. It is nice if the amplifier has at least two ranges in order to be more flexible in measurements. A typical appliion for lowfrequency measurements is the paper mill rolls. They have a frequency of 15 Hz, where the user would need a sensor with Hz or less bandwidth.
