Abstract-This paper presents a new method to produce and control the vibration amplitude and direction of a travelling wave in a finite beam, using multi-modal approach. A closed loop control of the transducer vibration is applied using vector control method. the modelling in rotating frame and the decoupling according to two-axis allows to obtain a double independent closed loop control. This allows to regulate the vibration amplitude of the travelling wave directly. An analytical modelling is presented, with experimental validation, showing good performances even in the presence of perturbations.

“…Roopa Rani et al studied the displacement, stress, and heat specification of various horns with different cross-sectional shapes through experimental and analytical methods, and Nguyen et al developed a horn with a B-spline cross-sectional shape and further investigated its characteristics [16,17]. In addition, many researchers have investigated the displacement and frequency characteristics of various ultrasonic machines considering the geometrical characteristics of the horn, but it was a single-material ultrasonic horn and blade, and they did not even consider the various geometrical design variables simultaneously [7,[18][19][20][21][22][23][24][25][26].…”

We developed and optimized a block-type ultrasonic horn that can be used for cutting hard materials. The proposed block-type sonotrode consists of an aluminum horn and a tungsten carbide blade to increase the cutting of hard materials. We designed an initial ultrasonic block horn that has double slots and an exponential stepped profile. We developed a finite element model of the initial model and analyzed the characteristics of natural frequency and displacement. We formulated a DOE table and response surface to perform sensitivity analysis and analyze the correlation between the design variables and characteristics of the proposed block horn. The optimal ultrasonic block horn was derived via a multi-objective optimal design problem to maximize the amplitude uniformity of the proposed horn and frequency separation. We fabricated the optimal block horn and verified it experimentally. An ultrasonic cutting experiment was conducted to find the ultrasonic cutting force with hard ceramic composite materials. A cutting test with a conventional cutting machine under the same condition was also conducted to compare the cutting force. The proposed optimal ultrasonic cutter requires 70% less cutting force than the conventional cutter to cut a ceramic composite material and the cutting surface with the application of the proposed optimal ultrasonic cutter is much cleaner with no crack and delamination than that with the application of the conventional cutter.

“…2) was chosen in order that earlier researches showed, that stepped shape waveguide has highest amplitude magnification factor of the generated vibrations (comparing to cylindrical, conical, exponential, reversed exponential shapes) and surface area with greater cross sectional area moves in the most uniformity way in the longitudinal direction when excitation conditions are the same [8].…”
