Based on the analysis and inquity into the governing equation its solutions for the longitudinal vibration of variable cross-sectional bar,some fundamental formulas used analytically in designing and analyzing the ultrasonic vibration systems are given.
In this paper,the energy method is adopted. By means of analyzing the effect upon the kinetic energy of vibration system caused by cross-coupling, the amended formula for natural frequency of the longitudinal vibration rod with variable cross-section is obtained.
The Research on the Longitudinal Vibrations System of the Composite Ultrasonic Motor
In this paper,firstly the design theory about longitudinal torsional composite type ultrasonic motor is put forward Meanwhile,it is also pointed in the paper that the main reason difficult to realize the mode degeneracy of motors is the low precision of Longitudinal vibrations system model Based on the experimental research,that how the longitudinal and torsional vibrations change in the neighborhood of their resonant frequencies is analyzed,and the reason of why the resonant nonresonant frequent running motor can also output the high torque are described
The results show a significant correlation between ES, transverse vibration DMOE (EF), and longitudinal vibration DMOE (EL).
Convective flows of a nonuniformly heated fluid in a cylindrical fluid zone in a high-frequency longitudinal vibration field are studied.
Dynamics of a two-fluid system in a rotating horizontal cylinder under longitudinal vibration
In order to match the resonance frequencies of longitudinal vibration and torsional vibration excited in the stators, a symmetrical structure was adopted in design of the motor.
A finite element model was developed using ANSYS software for the purpose of analyzing the resonance frequencies of longitudinal vibration and torsional vibration as well as the function of the adjusting rings.
The Mobius trasformation is applied to anaylyze the loaded amplitude transformer in a high power ultrasonic system. Several features of the vibrating horn can be predicted from the mapping: the dependence of the input impedance on the load impedance, the points of equal impedances, the condition of resonance and the working stability Limited experimental verification has been effected.
In ihis paper, a longitudinal vibration problem on bars is solued in seven various ways.
Since the vibration behaviours of a piezoelectric vibration system change with an electrical load, the Vibration of such a system will be damped, when the electrical load includes a resistance component. Based on this effect, a principle of piezoelectric damping of vibration is developed.
