Optical method in diagnostic of transient dynamic responses in human skull
Dvořáková, Pavla ; Trnka, Jan ; Veselý, Jan
The paper deals with the study of stress wave propagation in a human skull. Impact was generated both focused ruby laser beam and exploding wires. Transient dynamic responses were studied by means of double pulse holointerferometry and laser interferometry. in the research was paid attention to the evaluation of stress wave propagation velocity and tha result of both optical methods were compared. The study assists in the design of useful medical solutions.
Výzkum šíření napěťových vln v lidské lebce metodami optické interferometrie
Trnka, Jan ; Veselý, Jan ; Dvořáková, Pavla
The paper deals withthe research of stress wave propagation in the human skull. Transient state is generated by exploding wires. The response on impact loading is evaluted by double-pulse holointerferometry and by laserinterferometry.
Time-domain identification of non-linear reological models in a sandwich mechanical system
Pešek, Luděk ; Veselý, Jan
The vibration control by passive damping of dissipation layers is considered. The methods for mathematical description and parameter identification of weakly non-linear dissipation behavior of rubber layers in time domain are designed.
Shape of the human vocal folds in a defined phonation position
Horáček, Jaromír ; Švec, J. ; Klepáček, I. ; Vetešník, A. ; Veselý, Jan
The paper presents experimental investigation of aerodynamic shape of the vocal folds measured in a defined phonation position with excised larynges. The vocal fold vibrations were excited by airflow and monitored acoustically, by means of laser vibrometry, pressure transducers and stroboscopy techniques. Method for casting laryngeal cavities for determining the vocal fold shape was developed. By the optical topography and the electron scanning microscope the shapes of the vocal folds were analysed.
The contribution to modal analysis of light structures with correction to additional transducer mass
Pešek, Luděk ; Veselý, Jan
This contribution deals with the correction of measured FRF's to additional mass represented by moving mass of transducer which makes identification of eigencharacteristics more accurate. The correction is aimed at the change of eigenfrequencies by me
Measurement of the vocal-fold vibration
Horáček, Jaromír ; Švec, J. G. ; Veselý, Jan ; Vilkman, E. ; Klepáček, I.
The study presents the measurement set-up and selected results of experimental investigation of various dynamics and phonation characteristics of human vocal folds. The experiments performed with excised larynges were focused mainly on study of non-li or vibration effects and on creation of plaster castings of the larynx in a defined fixed phonation position.
Resonance properties of human vocal folds-examination in vivo
Švec, J. G. ; Horáček, Jaromír ; Šram, F. ; Veselý, Jan
The paper investigates dynamic characteristics (resonance frequencies and resonance modes of vibration) of living vocal folds. Vibrations of the vocal folds, excited externally using a shaker, were observed by means of a rigid endoscope and visualized using the methods of videostroboscopy and videokymography.
Experimental study of the vocal-fold vibration in excised larynx: measurement set-up and techniques
Horáček, Jaromír ; Švec, J. G. ; Veselý, Jan ; Vilkman, E.
The study presents the experimental arrangements and methodology for measuring the dynamic and phonation characteristics of human vocal folds. The experiments were focused mainly on non-linear vibration effects when bifurcation appears during phonation by changing, for example, the tension of the vocal folds.
Dynamic behaviour of the human skull
Horáček, Jaromír ; Veselý, Jan ; Trnka, Jan ; Veselý, Eduard ; Vohradník, M.
Original experimental results of the vibration modal analysis, time-average and double pulse holography measurement of the human skull are presented. Two different skulls were tested in the laboratory and the results of both measurements are compared. The influence of the soft tissues was modelled as well.
