Návrh dvounápravového podvozku traktorového nosiče / Design of two-axled undercarriage for tractor trailer

Pučálka, Lukáš January 2008 (has links)
Barter system super - structures in the area agriculture shows like most effective way of transport materials. Single-level memory exchange super - structures, that's biggest trump for higher effectiveness investment that the consumer will do. Work treat of in many ways structural design on the part of using and driving quality.

Vytvoření cenových podkladů pro stanovení tržního nájemného v bytech pro lokalitu Brno - Královo Pole / Creation of Pricing Details for the Determination of Open-market Rent for Apartments for the Brno-Královo Pole Locality

Vrbková, Lucie January 2011 (has links)
The goal of this diploma thesis was creation of pricing details for the determination of open-market rent without regulation of prices for apartments for the Brno – Královo Pole locality. As a basis for diploma were used data of achieving market rents taken from databases of two estate agencies. Apartments were divided into categories according disposition on small, middle, large and luxury. In each category was defined a standard from which was basic price made. After that were created twelve groups which enabled to judge influence of each factor on rent. As a factor (quantity) influencing a rent were defined – state of property, characteristic type of construction, equipment of apartment. As a result was total summary of basic rental prices for each categories relating to floor area and was defined influence of each factor.

Využití optimalizačních algoritmů při návrhování konstrukcí / Using Optimization's Algorithms by Designing of Structures

Fedorik, Filip Unknown Date (has links)
The application of optimization algorithms in the design of many economical and industrial problems currently represents a significant assignment. The development of high-powered computers allows an application of difficult mathematical techniques and physical phenomena to simulate real problems with sufficient accuracy. The optimization techniques used in engineering designs are mostly represented by modified mathematical programming methods with extension of their usability. The aim of the presented thesis "Using Optimization´s Algorithms by Designing of Structures" is to analyze the applicability of optimization procedures which are available in the widely used computing system ANSYS in civil and mechanical engineering practice. The numerical analyses were performed within the frame of multi-extreme, one to three dimensional optimization problems, multi-dimensional problems expressed by minimizing the weight of a truss beam and efficient design of air gap location in wooden studs from the point of view of thermal features of the structure. The analyzed optimization processes are in plurality verified with accurate manual computing and graphical solutions and the accent is put on optimization methods´ possibilities to improve robustness, efficiency and accuracy of the optimization algorithms in civil engineering problems´ designs. The optimization methods represent a suitable approach to improve the efficient design of a wide range of civil and mechanical engineering structures and elements. By combination of their advantages and FEM/FEA method it is possible to achieve very good results, although robustness of the solutions is not guaranteed. The robustness and accuracy of the procedure could be increased by competent exploration of design space and suitable selections of optimization methods´ features.

Softwarová podpora návrhu a hodnocení výměníků tepla se svazkem trubek v plášti / Software Aided Design and Assessment of Shell and Tube Heat Exchangers

Létal, Tomáš Unknown Date (has links)
Subject of this work is a development of an integrated software environment for mechanical design and check of shell and tube heat exchangers. Processes of mechanical design and checks well as software which perform these processes are broken down to basic methods and parts. Mechanical design is usually performed according to some standards. In this work, ČSN EN 13445 is used. This standard describes mostly design check calculations which can be easily algorithmized. On the contrary, design calculations are described to some extent in few simple cases and mechanical design of shell and tube heat exchanger has not been fully algorithmized yet. Subject of this work is design of software, which will be capable of automatically performing mechanical design from datasheet as an input. Based on breakdown of design and check processes, requirements for key software features are derived. Important part of presented work is design and implementation of key modules – data model of shell and tube heat exchanger, module for mechanical design check according to ČSN EN 13445. These modules form basis of the software which will be developed further in future work.

Optimalizace konstrukčních detailů jednoplášťových plochých střech / The Optimization of Structural Details for Flat Single-leaf Roofs

Matějka, Libor Unknown Date (has links)
This thesis deals with the optimization of structural details for flat single-leaf roofs. In the first part of the thesis, 3 groups of structural details for flat roof (flat roof parapet, gutter at flat roof without overhang of the roof cladding, intersection of the flat roof and vertical supporting structure) are characterized, classified and examined. In every group one of these structural details is designed with use of modern composite material based on secondary raw materials (still in development process). The theory describes the current issue of thermal bridges at constructions and applicable legislative documents. The next part introduces thermal engineering analysis (based on finite element method) of structures with annotated data outputs. The another main part of thesis provides with designed innovative optimization algorithm using multi-criteria decision analysis methods, which is then practically tested on the surveyed construction details. The conclusion summarizes the results and provides with improvements based on completed research.
