Dynamic Analysis of Cone Waveguide for Ultrasonic Assisted Technological Processes

Abstract

Research and development of new materials (ceramics and composites) with advanced mechanical properties also leads to the development and application of new so-called hybrid technological processes, which are based on a combination of conventional technological processes with ultrasonic tool vibrations. The fundamental condition for the optimal realization of technological process is the vibration of ultrasonic waveguide in the resonant state. Therefore, the ultrasonic waveguide must have the required modal properties, which depend on the distribution of its mass and stiffness properties. Design and analysis of dynamic properties of ultrasonic cone waveguide with adaptive modification of modal properties is presented in this paper. Modification of modal properties is performed using an embedded core, which changes the distribution of spatial properties of the waveguide structure. The effect of geometric parameters and material properties of the inserted core on the ultrasonic waveguide modal properties (mode shapes, natural frequency, amplification factor) is presented.
