This paper deals with the electro-mechanical transfer functions of an ultrasonic wheel system. The objective is to initiate a mode that can produce certain relative dynamic responses in the proposed ultrasonic wheel system. The performance will be parameterized by system inputs in an attempt to obtain an optimal operational configuration. The electromechanical transfer function model of the piezoelectric ultrasonic wheel based on the lateral elliptical motion is derived for the control application and certification of its load-characteristic parameters and also predicts the wheel system performance. On this basis, we can determine whether the output of the wheel system will be stable. The contact-dynamics behaviors of the stator are also studied. These derived formulations in this paper are based on the general concept of the constitutive laws governing piezoelectric materials which permit the introduction of kinetic energy, electrical energy, and geometric constraints relating to the deformation variables.
