Virtuální model rezonančního adhezního testu závěsu kola dle EUSAMA / Virtual model of resonance adhesion test (EUSAMA)

Hortová, Petra January 2009 (has links)
Thesis deals with problems about areas of a non-assembling diagnostics namely resonant adhesive tester according to an EUSAMA methodology. Result of the methodology is a technical condition examination of dampers. However with regard to testing of whole suspension and damping vehicle system are results distorted by influence of testing conditons and another vehical components. Goal of thesis is analysis limits of practical use resonant adhesive tester for a quality checking of mount wheels damping. Problems are solved by a virtual simulation in a program Adams/View where is created a real model of vehical axle of Skoda Roomster TDI 1.4. In the model is consequently simulated possible functional characteristics and abrasions of single components which influence the methodology. Virtual model will be using for research activity of Institute of machine and industrial design Faculty of mechanical ingeneering Brno University of technology.

Análisis y diseño comparativo entre un edificio con amortiguadores de masa sintonizada y un edificio convencional en la ciudad de Chiclayo

Llontop Izquierdo, Kevin Antonio January 2023 (has links)
Perú está ubicado en uno de los continentes que presentan mayor actividad sísmica causando muchas pérdidas humanas y daños excesivos en elementos estructurales y no estructurales, así mismo para disminuir estos movimientos sísmicos se ha estudiado un sistema de protección sísmica llamado Amortiguamiento de masa sintonizada con el fin de aumentar el desempeño sísmico, El edificio analizado es: las dos torres de Salaverry ubicado en la ciudad de Chiclayo del territorio Peruano, Dicho amortiguamiento de masa sintonizada se ha colocado en la parte final del edifico con el propósito de disminuir los desplazamientos laterales ,Los Análisis utilizados han sido el Estatico,Dinamico Y el Análisis tiempo historia cumpliendo también con los requisitos de la Norma E030 , Para el análisis tiempo historia se han seleccionado los sismos ocurridos en Piura el 18 de octubre de 2021 y el 3 de febrero Condorcanqui Amazonas y uno de los sismos más fuertes de Perú que es de lima 1974, de los resultados obtenidos se ha concluido que este sistema de amortiguamiento de masas sintonizada al incorporar a edificios reduce considerablemente los desplazamientos laterales, resultando ser uno de sistemas de protección sísmica favorable / Peru is located in one of the continents that present the greatest seismic activity, causing many human losses and excessive damage to structural and non-structural elements. Likewise, in order to reduce these seismic movements, a seismic protection system called Tuned mass damping has been studied in order to increase the seismic performance, The analyzed building is the two Salaverry towers located in the city of Chiclayo in the Peruvian territory, This tuned mass damping has been placed in the final part of the building with the purpose of reducing lateral displacements, The Analyzes used have been the Static, Dynamic and Time History Analysis, also complying with the requirements of Standard E030. For the time history analysis, the earthquakes that occurred in Piura on October 18, 2021 and February 3, Condorcanqui Amazonas and one of the strongest earthquakes in Peru, which is from Lima 1974, of the results obtained It has been concluded that this tuned mass damping system when incorporated into buildings considerably reduces lateral displacements, turning out to be one of the favorable seismic protection systems.

Magnetoreologický tlumič pro formuli Student / Magnetorheological damper for Formula Student

Dlápal, Václav January 2019 (has links)
The master thesis deals with design, manufacturing and testing of a prototype magnetorheological damper developed for Formula Student vehicle. The aim was to design and test the damper with similar damping properties to the vehicle as a conventional damper has. Target force-velocity curves were set using quarter car model and evaluated comparing minimal contact force of a tyre for conventional and newly developed damper characteristics. Structural analysis of designed parts, hydraulic and static magnetic analysis were performed. Manufacturing of a specific part magnetorheological damper part was described – piston. Manufactured prototype damper characteristics were evaluated.

Virtuální model dokmitového testu závěsu kola / Virtual model of manual tail test

Greplová, Kristýna January 2009 (has links)
The aim of the master´s thesis is analysis of limits of tail test exercise in practice for certification of dampening quality of wheel hitches of vehicles using virtual simulation. The goal is to create virtual model of front axle of Skoda Roomster 1.4 TDi using program Adams/View, MSC Software and follow-up simulation of tail test of wheel hitch.
