Design of the ROPS protective frame
Zimek, Rostislav ; Machálek, Jakub (referee) ; Pokorný, Přemysl (advisor)
This thesis deals with the design of the protective frame protecting occupants in rollover (ROPS). The creation of the calculation model, in order to perform a stress-strain analysis of the frame under the conditions of the homologation test. Execution modal analysis with the inclusion of the mass of the auxiliary device. A motion for a protective frame is designed so that it can be subjected to destructive test according to standards ČSN EN ISO 3471. The strength and modal analysis was carried out using the finite element method (FEM). The diploma thesis was conducted in cooperation with the company, the Tatra Truck a.s.

Strength analysis and optimization of the two-way excavator MH Plus S cab
Zavadil, Milan ; Janich, Miroslav (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with stress analysis and optimization of two-way cab excavator MH Plus S with total weight of machine 19375 kg. Stress analysis has been performed using the finite element method (FEM). As next step the structure design of protective frame and strength analysis of the cab and protective frame, which protect crew when the machine is rolled over protective structure (ROPS) according to ČSN EN ISO 3471 standard, have been made. The design documentation is a part of diploma thesis. This diploma thesis was conducted in cooperation with the firm Agrotec a.s.
