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.

Inclined belt conveyor of aggregates
Zavadil, Milan ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this work is the design of helical conveyor belt for transport of building stone and recycled aggregate with a maximum grain size of 150 mm. Work includes a characteristic of some parts of the conveyor functional calculation, determine the key dimensions and design of power according to ISO 5048. Further strength calculation was carried out certain parts of the conveyor and assembly drawn in overall conveyor subassembly and stretching equipment.
