Design of body assemblies with distributed tasks under the support of parametric associative design (PAD)

Tecklenburg, Gerhard January 2011 (has links)
This investigation identifies how CAD models of typical automotive body assemblies could be defined to allow a continuous optimisation of the number of iterations required for the final design and the number of variants on the basis of Parametric Associative Design (PAD) and how methodologies for the development of surfaces, parts and assemblies of the automotive body can be represented and structured for a multiple re-use in a collaborative environment of concept phase of a Product Evolution (Formation) Process (PEP). The standardisation of optimised processes and methodologies and the enhanced interaction between all parties involved in product development could lead to improve product quality and reduce development time and hence expenses. The fundamental principles of PAD, the particular methodologies used in automotive body design and the principles of methodical development and design in general are investigated. The role which automotive body engineers play throughout the activities of the PEP is also investigated. The distribution of design work in concept teams of automotive body development and important methodologies for the design of prismatic profile areas is critically analysed. To address the role and distribution of work, 25 group work projects were carried out in cooperation with the automotive industry. Large assemblies of the automotive bodies were developed. The requirements for distributed design work have been identified and improved. The results of the investigation point towards a file based, well structured administration of a concept design, with a zone based approach. The investigation was extended to the process chain of sections, which are used for development of surfaces, parts and assemblies. Important methods were developed, optimised and validated with regard to an update safe re-use of 3D zone based CAD models instead of 2D sections. The thesis presents a thorough description of the research undertaken, details the experimental results and provides a comprehensive analysis of them. Finally it proposes a unique methodology to a zone based approach with a clearly defined process chain of sections for an update-safe re-use of design models.

Návrh předpjaté nádrže / Design of reinforced tank

Štramberský, Martin January 2014 (has links)
The matter of this diploma thesis is a static storage tank for petroleum substances, the study of a solution for appropriate shape of shell and its effort to dihedral for roofing, and the study of effect of the storage of inner roofs walls of the tank to the size of the internal forces. The internal walls are carried out by the method of finite elements in the engineering program Scia Engineering 2013 and on the basis of it, designing of the framing sections of the tank. There is a calculation part of the lower horizontal bias wreaths of the shell and internal supporting wall. All the components are assessed on the 1st limit state of the load-bearing capacity and the 2nd limit state of the application (emergence cracks, limiting voltage in the concrete and a prestressing steel). The existing external wall is assessed only on the marginal status load of carrying capacity. The part of diploma thesis is also drawing documentation, accompanying report and technical report. The goal of the diploma thesis was to design the tank without an occurrence of the cracks in the concrete so as the vertical wall was prestressing only in the horizontal direction and the optimal proposal roof tanks as an addition.

Konstrukce sila na cukr / Sugar storage tank

Kotík, Libor January 2015 (has links)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.

Transnational Corporations and Human Rights : Assessing the position of TNCs within international human rights law, and the appropriateness of an international treaty on business and human rights

Söderlund, Erik January 2018 (has links)
Transnational corporations are playing an important role in the global economy of today. Many of these corporations have great economic resources and have the possibility of contributing to the development of societies in developing states. At the same time, in their search for profit, the activities of TNCs have proven fatal to some of the individuals employed by them, or otherwise in contact with their activities. Within the international legal framework, corporations are not traditionally treated as subjects and if a TNC allocates its production to a state with lax human rights protection, no binding international standards exist to regulate the conduct of the corporation.  In my thesis I will assess the position of TNCs under the present core human rights instruments and soft law initiatives. I will also analyze a draft treaty text produced by the Intergovernmental Working Group on Business and Human Rights, released in July 2018, to reach a conclusion on whether such an instrument would affect the international legal status of TNCs and provide a more robust protection of international human rights.

Příprava realizace polyfunkčního domu v Pardubicích / Realization of a polyfunctional building Pardubice

Výborný, Václav January 2016 (has links)
The main contens of the thesis is solving a construction-technological project substructure and the upper shell construction of a polyfunctional building in Pardubice. Excavation and foundation work are done in section A and B1 and B2. Drilled piles are foundation of a polyfunctional building. Drilled piles are support of reinforced concrete grillage, which are from strips foundation and foundation pads. Cast-in-place concrete frame is a form of load-bearing structure, which contens plate ceilings, pillars and walls. Peripheral masonry is from hellow clay blocks, which are between cast-in-place concrete frame. Diploma thesis includes technical report, plan of building side, schedule and the budget of the building, technological instructions, radon prevent, control and testing plan, safety, balance resources, selected constructional details, machinery composition, bill of quantities.
