Özet:

Thanks to their features such as fast response and low energy demand, materials with piezoelectric properties are often used as detectors and stimulants. Since the vibration characteristics play an effective role in the working principles, it is important to know the vibration characteristics of piezoelectric materials. In this study, a compulsory vibration analysis of a piezoelectric bar that changes the cut pleasantly was made. The differential equation that expresses the problem has variable ratioes that function mechanical and electrostatic characteristics. As the analytical solution of this type of linear differential equation is limited to some specific cutting fields, numerical resolution is not missing. The console with a pleasant cutting area is achieved in the mathematical model Laplace space for the PZT-4 forced vibration of the piezoelectric bar and is numerically solved by the Complementary Functions Method. The transformation of solutions into time space was carried out by applying the Durbin method of modification. The solution method also applies to the uniform piezoelectric bar, which can also be analytically solved. A number of examples have been given to show the impact of pleasant cutting change on the dynamic behavior of the bar
