A design of single-purpose saw
Rakhmatullin, Artem ; Štěpánek, Vojtěch (referee) ; Tůma, Jiří (advisor)
This thesis focuses on the design of a single-purpose saw for cutting grooves on aluminum profiles. The work includes the examination of different types of saws, the examination of various design alternatives, the identification and selection of the most advantageous variant, the subsequent creation of a detailed design based on the chosen solution and a comprehensive evaluation of the resulting design. The desired result is a saw design that prioritizes factors such as ergonomic comfort, safety, precision and operational efficiency, ensuring a complete and efficient solution.

Design of a Crash-Test Dummy
Sedláčková, Martina ; Coufal, Tomáš (referee) ; Bilík, Martin (advisor)
The main objective of this thesis is construction of crash test dummy for vehicle-pedestrian crash tests. There is review of nowadays used crash test dummies types in the introduction of this thesis. This is followed by part describing construction itself. Chapter about construction begins by characterizing of used materials features in relation with real human body physiology. Main part of chapter is describing construction of crash test dummy’s skeleton and its individual components including 3D modelling and strength analysis. Thesis is finished by cost assessment.

Wing system design of competition aircraft
Mahdal, Vít ; Hájek, Tomáš (referee) ; Katrňák, Tomáš (advisor)
This bachelor’s thesis deals with the wing system design of competition aircraft. The thesis consists of five main parts. The first part is an introduction to the competition – Air Cargo Challenge, and the mission of UAV. The second part details the compilation of flight envelope and loads acting on the aircraft. Part three describes stress analysis of the old fabric method of wing construction. Part four of the thesis gives suggestions of a new wing system design, and its stress analysis. The final part of this bachelor’s thesis describes the advantages and disadvantages of the new system design, and compares them to the old version.

Replica Design of L-40 "Meta Sokol " Aircraft - wing
Pluhař, Tomáš ; Jebáček, Ivo (referee) ; Píštěk, Antonín (advisor)
This diploma thesis targets in concept of wing, aileron, flap and main undercarriage of the ultralight replication of the plane L-40 called Meta Sokol. The thesis developed from cooperation with two other members of the team – Alice Lipková (aerodynamics, power) and Miroslav Růžička (fuselage, tail unit and rear gear). The first part of this diploma thesis is concerned with load and concept of structure of the wing. At first the flight envelope is specified, then charakteristics of shearing force, bending moment and torsion moment are determined spanwise. The concept and subsequent strength verification of structure of the wing is also solved. The same process is claimed to concept of the aileron and the flap. The second part of this diploma thesis is dealt with main landing gear, its support, structure, springing and the principle of retraction. The final passage is devoted to load of the undercarriage.

Risk analysis of pest infestation of wooden structures
Brada, Stanislav ; Hunková,, Veronika (referee) ; Šebesta, Petr (advisor)
The thesis deals with risks of defect occurrences in a wood construction. Wood constructions and their parts are exposed to a number of negative factors influencing their lifetime. The aim of the thesis is to give an outline of risks of defect occurrences in a wood construction attacked by pests and propose measures for their elimination.. These steps are closely described in the individual parts and processes. Part of the thesis is the FMEA analysis, resulting in appropriate chemical protection, a factor considered before incorporation into the construction. The analysis and its outcomes are important for improvement of the wood construction lifetime.
