Lubricants for bicycle chains
Brychta, Ondřej ; Navrátil, Václav (referee) ; Svoboda, Petr (advisor)
This bachelor thesis deals with the lubrication of bicycle chains. The introduction describes the basics of the friction processes, then there is an analysis of the chains used on bicycles, used materials, analysis of forces and wear in the chains. The last part is devoted to the properties of basic types of lubricants, their additives and the possibilities of their use in cycling.

Family house
Brychta, Ondřej ; Dohnal, Jakub (referee) ; Sedláková, Markéta (advisor)
The project technical documentation of a detached house with an establishment - massage room. The building is located in the village Rabštejn. Built-up area is 142.41 square meters. Detached house has two floors and one basement. In the basement is a business area for homeowners. The house is based on the underlying strip of plain concrete and walled building system Porotherm. The roof of the second floor is a warm flat roof with loadbearing structure of the panels Spiroll. The floor on the terrace in 1.NP and 2.NP is walkable flat roof with classical sequence of layers for the implementation of the terraces. Bachelor´s thesis include a sketch, a block plan, a building documentation, fire safety measures, a building physics, seminar work, calculations and technical data for some products.

Calculation of the aerodynamic characteristics of the SIGMA sports car
Brychta, Ondřej ; Čavoj, Ondřej (referee) ; Vančura, Jan (advisor)
This thesis deals with the problem of disturbing forces that act on the crew of the SIGMA vehicle, especially in the area of the driver's head and houlders due to air flow. In the practical part, a model for CFD simulations is designed, a general characteristic of the car's aerodynamics is created and a comparison of the base variant of the car with variants with aerodynamic shields, which eliminate this uncomfortable phenomenon without worsening the aerodynamic resistance of the vehicle.

Kompozitní materiál vyztužený skelnými vlákny s různou orientací
Brychta, Ondřej
The aim of this diploma thesis is an experimental comparison of mechanical proper-ties of composite materials reinforced with differently oriented glass fibers. These were samples of polyurethane resin with a needled mat, which is used in the floor of buses as a supporting element of floors. The theoretical part is focused on the composition, composition of fibers and distri-bution of individual types of composite materials and on determining the production method that can be used in the production of composite materials in various areas of industry. At the same time, a comprehensive methodology for recording failure of composite material during tensile loading was proposed in the experimental part. During loading, samples were monitored by the optical digital image correlation (DIC) method to identify deformations on the test samples. This method has become a suitable tool for evaluation and characterization of the deposition of individual fabrics in tested samples. Thanks to this me-thod, individual failures occurring during tensile loading were detected. These were divided into certain typical phases of composite material failure. The samples for the experimental part are samples of polyurethane resin reinforced with a needled mat. The reinforcement structure is composed of a total of 6 layers. It is a two-layer material composed of woven roving and chopped mat. On the back of the U-profile is reinforced with glass-roving.

Progresivní konstrukce míchačky stavebních hmot
Brychta, Ondřej
In my thesis entitled Progressive design mixers of building materials are mainly concerned with the design and construction of a gravity mixer of building materials for home use. The first part focuses on the distribution of mixers according to various criteria. The second part deals with the actual design and construction of the mixer, the capital and the biggest problem is the implementation of the drive that I chose by a worm gear.
