Experimental analysis of a fixed beam dynamic behavior
Poduška, Jan ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of dynamic behavior of a fixed beam. An analysis of the applied mathematical model is proposed in the work. The mathematical model is then realized in MATLAB programming environment. Modal frequencies and mode shapes are con- sequently computed and results are compared to those obtained from the experimental modal analysis.
Modelling of vibration of dynamic systems with n-degrees of freedom
Horák, Petr ; Hadaš, Zdeněk (referee) ; Dušek, Daniel (advisor)
The aim of this work is to assemble mathematical model for given system of point masses. Compute the natural frequencies and their corresponding modes of vibration. Differentiations of vibration by various points of view are written in this work. The given system is analyzed and the equations of motion using two most common methods are written. Calculation procedure of mentioned physical quantities is written in order from simplified to complete system of point masses. This procedure is used in command file to express values numerical. The frequency response of the system and the displacement-time plots are shown. The impact of constant variability entering the calculation is described.
