Stability of piezoelectric material for suspension applications

Piezoelectric materials have wide range of applications in the field of aerospace and automobile industry because of their ability to generate electric potential, response to mechanical signal as well as response to electric signal. An analytical model is constructed in this research work, this model is based on the shocking conditions that an automobile vehicle face in real time and the response of piezoelectric material to that mechanical shock. To find the response of smart structure i.e., Lead Zirconate Titanate (PZT-5A4E) to variable mechanical shocks for general automobile. Numerical simulations are carried out to determine the accumulative effect of the specified conditions and to analyze the stability of an automobile control system. This model provides novel mechanism for characterizing PZT-5A4E for smart structures using stability; validated by Nyquist Theorem and RH Table. The analytical model designed is stable for specified conditions.
