Experimental and numerical investigation of the frequency-modal properties of the switch box
Zolotarev, Igor ; Pešek, Luděk ; Bula, Vítězslav ; Šnábl, Pavel ; Gabriel, Dušan ; Mračko, Michal ; Masák, Jan
The research is linked to increase of seismic resistivity of data board switch boxes. Therefore we deal with numerical modelling of the box for finding the hot spots and designing appropriate modifications. This paper deals with numerical and experimental frequency-modal properties of the switch box and mutual comparison for numerical model validation.
Experimental investigation of the frequency-modal properties of the measuring container for LUNA mission
Zolotarev, Igor ; Bula, Vítězslav ; Šnábl, Pavel ; Snížek, Jan ; Souček, Jan
This paper continues investigations of the measuring equipment for space missions. The frequency-modal properties of the measuring container for LUNA mission were obtained by experimental investigation.
Modal analysis of a container with measuring equipment for space mission
Zolotarev, Igor ; Bula, Vítězslav
This paper continues investigations of some measuring equipment for space mission. The frequency-modal properties a container with several slots and measured desks are studied. The natural frequencies and corresponded modes obtained using measuring methods are presented for several combinations of the container components.
