Impact hammer calibration
Šafář, Jakub ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
The aim of this thesis is verification of sensitivity of an impact hammer ENDEVCO 2302-5. The tesis also discusses the possible negative influences of the experiment. Calibration of an impact hammer was performed using known mass.

Impact hammer calibration
Bilík, Šimon ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
The theoretical part of this thesis focus on the description of the piezoelectric accelerometers and their use for the impact measurements. It also characterizes the construction and the calibration process of the impact hammers with the use of the piezoelectric accelerometers. The practical part describes the place of calibration with the calibration tools, identifies the source of the oscillations on the output signal of the accelerometer and suggests its compensation. Part of the thesis is a service program for the impact measurement, analysis and the impact hammer calibration. Thesis also describes the methodology of the calibration and quantifies the measurement uncertainty.

Automatic Modal Hammer
Bomský, Michael ; Čala, Martin (referee) ; Beneš, Petr (advisor)
The aim of this work is to design and then construct a solution to automate an impact hammer, which is used for vibration (modal) analysis of various mechanical parts. It is almost impossible with the hammer to achieve the same place of impact, speed and power when used manuály. With automatization of this process it is possible to achieve precise and repeatable results.

Impact Hammer Calibration
Bilík, Šimon
This paper describes the construction of the calibration station for the impact hammer Endevco 2302-5 and it explains the influence of the impact mass on the calibration process. Based on the previous bachelor thesis [1] it also explains the origin of the oscillations on the accelerometer output signal described there and it suggests the improvements of the calibration process.
