This thesis deals with the simulation modelling of manipulator mechatronic system in ADAMS. The beginning of thesis is dedicated to the theoretical study of the compute modelling electro-mechanical systems and mechatronics approach modelling manipulator’s systems. Next chapters describe the creation of kinematics model of the manipulator with using ADAMS and proposal supporting frame in ANSYS/Workbench environment. The next step, manipulator and supporting frame simulation model is created for the computing vibration a dynamic analysis. At the end of this thesis is used cosimulation ADAMS and Matlab/Simulink for the control of synchronous drivers of manipulator.

The aim of this work was to propose an analytical spindle lathe and perform simulations to verify that the spindle is designed correctly. After calculations and modeling of the whole assembly, I began to make the first simulation in ADAMS. I proceeded from simple models over difficult to the final version of the entire assembly. I examined whether they match the values of power, speed, strength and other values with the values obtained analytically. The results of my works are virtual models of spindle, which can simulate various stressful conditions under which we can decide whether the spindle is satisfactory or not.

Though the Cotton Valley Group is productive in Mississippi, Louisiana, and Texas, little is known about production potential of the Bossier Formation (Lower Cotton Valley Shale) in southwest Mississippi. The Bossier Formation in Jefferson County, Mississippi is an organic-poor, carbonate-rich mudrock with siliciclastic intervals. Examination of cuttings by petrographic and scanning electron microscopy revealed fractures that have been filled by calcite and poreilling pyrite. Porosity exists within and around pyrite framboids, in unfilled fractures, and within peloid grains. Organic matter is rare in Lower Cotton Valley samples suggesting it is not self-sourcing. Total Organic Carbon (TOC) values are low (0.86-1.1% TOC) compared to the productive Haynesville Shale Formation (2.8% TOC). Porosity of the Lower Cotton Valley Shale is low (2.5- 4.2%) compared to productive Haynesville Shale Formations (8-12%). With current technology and gas prices, the Lower Cotton Valley Shale in Jefferson County, Mississippi does not have production potential.

Often mischaracterized as a sedate, muddled, and issueless personality contest, the U.S. presidential election of 1824 actually proved an important transitional contest between the First and Second American Party Systems. The five very active candidates involved in the contest created dynamic organizations, sponsored energetic newspaper networks, staged congressional legislative battles, and spread vicious personal attacks against each other, presaging the tactics of the more-celebrated succeeding 1828 election. Four key developments determined the outcome of the 1824 contest. One, the decline of the opposition Federalists encouraged the Republican Party to fracture into five competing candidacies. Two, Secretary of War John C. Calhoun's vicious political attacks fatally undermined the campaign of frontrunner Treasury Secretary William H. Crawford. Three, political outsider General Andrew Jackson successfully equated the practice of politics with corruption, capturing a plurality of the popular vote by running against Washington politicians. Four, Secretary of State John Quincy Adams' superb insider deal-making ability undergirded his successful effort to win the required House election once no candidate received a majority of electoral votes from the popular election. While adversely affecting the political careers of all the participants except Jackson, the election of 1824 accelerated the ongoing trend toward democratized presidential elections and helped give birth to the Second American Party System. / History

This thesis explores the influence of Alexander Hamilton upon the administration of John Adams. It begins with the background of the conflict between Adams and Hamilton, continues through Adam's presidency and ends with the "death of the Federalist party."

Analisa-se neste trabalho uma operação de montagem de um produto consolidado e em produção, utilizando-se técnicas de Sistemas Multicorpos (MBS). Para testar a viabilidade técnica desta proposta foi desenvolvido um estudo de caso numa empresa fornecedora de bancos para montadoras de veículos. Para tanto, foram comparados dados coletados do processo real na empresa, com resultados obtidos em simulações computacionais utilizando técnicas de modelagem e simulações de sistemas Multicorpos.

Die Mehrkörpersimulation (MKS) kommt in immer mehr Bereichen zum Einsatz. Bis vor einigen Jahren war das Thema fast ausschließlich im Automobilbereich wichtig. Heute wird der Ansatz in fast allen Bereichen der Technik, in dem „Bewegungsabläufe“ eine Rolle spielen, eingesetzt. Im Gegensatz zur Finite Elemente (FE)-Methode, für die eine detaillierte Bauteiltopologie mit einer Vielzahl von Elementen nötig ist, können mit MKS-Systemen selbst komplexe mechanische Systeme mit einer relativ geringen Anzahl an Freiheitsgraden abgebildet werden. Das Programm Adams hat diese Entwicklung maßgeblich mit gestaltet. Neben den Erweiterungen im Bereich der Solver und anderer mathematischer Formulierungen war immer die einfache Benutzerführung, die Integration von weiteren Simulationstechnologien und auch die Entwicklung von Spezialanwendungen ein wichtiges Thema der Entwicklung. Im Rahmen dieses Vortrages wird der Einsatz von Adams an Hand von Beispielen demonstriert. Weiterer Schwerpunkt ist die Erweiterung der Modelle durch Berücksichtigung der elastischen Materialeigenschaften einzelner Bauteile. Die Kopplung zur Lebensdauerberechnung an Hand von Beispielen schließt den Beitrag ab.

This work highlights the design process to build a MBD (Multi-Body Dynamics) model with flexible parts for a RCV (Research Concept Vehicle). Full vehicle dynamic simulations of the RCV model with flexible parts were performed for different load cases and the results were compared with that of a MBD model with rigid body components. In addition, FE modelling of the RCV body parts, selection of attachment nodes, generation and verification of Modal Neutral Files (MNFs) are discussed. RCV is a concept vehicle developed at KTH Royal Institute of technology as a research platform to implement, validate and demonstrate results of various research projects. The vehicle consists of body, suspension and tire subsystems which were designed and developed as individual projects. The body subsystem comprises of rollcage, subframe and a composite baseplate. In this project, a MBD model of the RCV was developed in ADAMS/CAR to measure the forces acting at the interface of these body components and also to consider the suspension forces acting on the individual front and rear subframe parts. Finite element (FE) models were incorporated to consider the flexibility of the body components. The RCV is a vehicle constantly evolving with addition of new components to implement and test various research results. To study the application of this method, two Models of the RCV with design modifications were developed and studied. A model of the RCV without rollcage and a model with a rigid link connecting the body components were built and the results of dynamic simulations were compared with that of the existing RCV design. When flexibility of the baseplate was considered in the models, an overall change in dynamics of the body components was observed. Further, observing the results from models with design modifications, it was evident that this method can be used to study the effect of these modifications on the dynamic behaviour of the vehicle. / Det här arbetet belyser konstruktionsprocessen för att bygga en MBD-modell (Multi-Body Dynamics) med flexibla komponenter av konceptfordonet RCV (Research Concept Vehicle). Fullständiga fordonsdynamiska simuleringar med flexibla komponenter utfördes för olika lastfall och resultaten jämfördes med en MBD-modell med stela komponenter. Dessutom diskuteras FE modellering av RCVs olika delsystem, val av kopplingsnoder, generering och verifiering av ”Modal Neutral Files” (MNFs). RCV är ett konceptfordon som utvecklats vid Kungliga Tekniska Högskolan, KTH, som en forskningsplattform för att implementera, validera och demonstrera resultaten av olika forskningsprojekt. Fordonet består av delsystemen; chassi, hjulupphängning, och däck, vilka har utvecklats tidigare i separata projekt. Chassit består i sin tur av delsystemen; ”rollcage”, ”subframe” och ”baseplate”. I detta projekt har en MBD-modell av RCV utvecklats i ADAMS/CAR för att simulera olika körfall och beräkna de krafter som verkar mellan dessa delsystem och att också studera skillnaden i belastning av främre resp. bakre ”subframe”. FE modeller importeradesäven till modellen för att studera effekten av elasticiteten hos komponenterna på fordonets beteende.RVC är ett fordon som konstant utvecklas med tillägg av nya komponenter för att implementera och testa olika forskningsresultat. För att studera tillämpningen av denna metod skapades två modeller av RCV med olika konstruktiva förändringar vilkas inverkan på fordonet studerades. En modell av RCV utan ”rollcage” och en modell med styv länk som förbinder olika delar av chassit skapades och resultaten av dynamiska simuleringar jämfördes med simuleringsresultat för den befintliga RCV-designen. När flexibiliteten hos basplattan beaktades i modellerna observerades förändringar i dynamiken hos chassit vad gäller vertikala förskjutningar och vinkelförskjutningar. Utifrån dessa simuleringar kan vi dra slutsatsen att den utvecklade metoden är användbar för att studera effekter av konstruktionsförändringar på det dynamiska beteendet hos fordonet.
