Shock severity comparison using Shock Response Spectrum and Pseudo-Velocity Shock Spectrum in LabVIEW
Štěrba, Radek ; Pikula, Stanislav
This article deals with the comparison of Shock Response Spectrum (SRS) and Pseudo Velocity Shock Spectrum (PVSS). Publicly available data as well as values from an implemented experiment are used. The experiment consisted of acquisition of accelerations when a model car hit various braking pads. The data was recorded and evaluated in LabVIEW and for this purpose the PVSS needed to be implemented in same programing environment. The results show that the impact severity rating can be seen from SRS as well from PVSS, but on the 4CP paper the results are much easier to spot.
Program for analysis and comparison of shocks
Štěrba, Radek ; Beneš, Petr (referee) ; Pikula, Stanislav (advisor)
This bachelor thesis focuses on the analysis of shocks using the Shock Response Spectrum (SRS) and Pseudo Velocity Shock Spectrum (PVSS) methods. The first part of the thesis describes the theory of both methods including the assessment of shock severity and compares their availability in programming environments. The aim of this thesis is to design and implement a program in LabVIEW to evaluate shock data using these methods. The program in LabVIEW allows the use of Matlab or Python to calculate and plot SRS and PVSS. Based on the plotted graphs, the severity of the impacts is assessed. In the practical part, an experiment is performed with the impacts of a model car on different brake pads. The results of the severity of the available impact data such as earthquake or punching bag as well as the data obtained from the experiment are summarized in the last section.
Shock Response Spectrum Testing With Shock Machine
Šindelář, Michal
Transient mechanical shocks cause dynamic stress in structures which results in defect or malfunction of exposed devices. A shock response spectrum (SRS) is used for characterizing an acceleration response of linear single degree of freedom system to these shocks. This paper is focused on presentation of the shock response spectrum derived from half-sine shock generated by shock machine.
