Hydrostatic drive of multi-purpose loader DAPPER
Vydra, Tomáš ; Merenda, Lukáš (referee) ; Škopán, Miroslav (advisor)
This thesis deals with design of hydrostatic drive for multipurpose loader and tool carrier DAPPER. At the beginning is research of different basic concepts and modern solutions to the problem, aided by a detailed description of competitive machine in the same performance category. Extensive comparison with other producers is included in the annexes to this thesis. Furthermore, a theoretical driving characteristic and its appropriateness is examined further on the basis of two model situations. The calculations of the individual components of the hydraulic circuit precedes drive kinematics analysis of articulated machine frame, on it final conception of hydrostatic drive is chosen. Firstly hydromotors and hydogenerator are chosen on the grounds of calculations then hydraulic hoses, filters and flow divider. Next chapters are aimed to calculations of hydraulic losses and thermal calculation of hydraulic circuit. Final part deals with introduction the final characteristics of drive. The practical parts of the work are assembly drawings with main power components and hydraulic schematic of drive.

Using tribodiagnostics in predictive maintenance in company practice
Trost, Daniel ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The thesis deals with the use of tribodiagnostics in predictive maintenance in corporate practice. It is generally dealt with maintenance, then tribodiagnostics in the company Škoda Auto a.s. Used offline and online diagnostic tools are described. Emphasis is placed on verifying the functionality of the newly purchased online filter unit. The experimental part is focused on detailed analysis of the above, including comparison of measurement results offline and online diagnostics. There is also an economic evaluation of savings obtained by operation the online filter unit. In conclusion, the tribodiagnostics recommendations are given for Škoda Auto a.s.
