Creating virtual vehicle traffic scenarios in the CarMaker
Jagnešák, Peter ; Repka, Martin (referee) ; Fojtášek, Jan (advisor)
This master’s thesis focuses on the use of the CarMaker simulation software to create realistic scenarios for virtual vehicle testing, which are important for the development and validation of advanced assistance systems and autonomous vehicles. Additionally, the thesis deals with the integration of the virtual environment with real testing data, which enhances the accuracy and efficiency of simulation tests. The goal is to provide insight into the possibilities and challenges of acquiring data from real sources and their subsequent use in virtual testing using the CarMaker software.
Utilization of Digital Twins in Automotive
Horuta, Šimon ; Fojtášek, Jan (referee) ; Repka, Martin (advisor)
This bachelor thesis deals with the utilization of digital twins in automotive industry. In the introduction, the concept of a digital twin is defined and then Industry 4.0 technologies used by digital twins are described. Furthermore, several examples of their application in the automotive industry are given. In the practical part, a simulation of a braking maneuver in virtual environment is performed and the functionality of this model is verified by real driving tests. As a result of the practical part, the graphs from the simulation and the real driving are compared.
Optimization of motocross sidecar chassis
Švihálek, Petr ; Fojtášek, Jan (referee) ; Tobiáš, Martin (advisor)
This bachelor's thesis deals with the design solutions of shock absorbers in the motorcycling discipline of sidecarcross. A research of various construction variants of shock absorbers was conducted, along with their measurements both in laboratory conditions and during training rides. The thesis explores the influence of basic adjustment elements of shock absorbers on their performance. The measurement results are analysed and presented using graphs illustrating the distribution of shock absorbers in the reaction area of normal compression and in the response area of the HS regulator. The theoretical part of the thesis provides basic information about sidecarcross, the history of shock absorbers, and their function. The practical part focuses on the installation of equipment and field measurements. The acquired knowledge is utilized to formulate recommendations for the optimal adjustment of shock absorbers, which can positively affect the riding characteristics and performance of racing specials.
Vehicle suspension design and testing methods
Šenkeříková, Veronika ; Tobiáš, Martin (referee) ; Fojtášek, Jan (advisor)
This bachelor's thesis is dedicated to suspension systems and their typology. Furthermore, the basic geometric parameters of these systems are discussed in the thesis. Types of suspensions (axles) are classified according to the interdependence of individual wheels. Subsequently, the thesis provides an overview of simulation software for chassis development and testing in the virtual phase of development. These are divided according to computational principles, result evaluation, and environment. The last section addresses issues related to chassis testing and its properties as a whole, testing individual chassis components to verify durability etc. The thesis includes specific representatives of testing conditions. For each chassis component, a representative from each chassis subsystem is selected. This thesis provides a current overview of methods and tools used in the automotive industry for development and testing. It demonstrates the importance of both virtual testing and testing on testbeds for already finished products.
