heal.abstract	The development and optimization of modern vehicles necessitate a comprehensive understanding of vehicle dynamics and performance. This master's thesis addresses the need for a robust simulation framework that encompasses various aspects of vehicle analysis, with a focus on racing vehicles. The research is motivated by the increasing importance of vehicle simulation in designing and evaluating vehicle performance, along with the existing gap in simplified simulation models that fail to capture crucial effects without advanced and complex tools. The primary objective of this research is to develop a wide-ranging simulation tool that enables engineers to analyse different aspects of vehicle dynamics and performance. The baseline vehicle used in this research is a prototype race car named “P19-Delia”, which was designed and manufactured by the Formula Student team of the National Technical University of Athens. This choice, made possible due to the author's significant involvement in the design and testing of this vehicle, enables accurate modelling and evaluation of the simulation results by comparing them with actual track data. It is important to note that the purpose of this selection is to provide an illustrative example rather than to optimize or design the vehicle within the simulation framework. The simulation tool incorporates both basic mass point principles and advanced modelling approaches, such as full-car models and Pacejka's Magic Formula, in specific areas like suspension dynamics and yaw moment diagrams. The complexity level of the modelling is carefully selected based on the specific simulation feature to ensure accuracy and relevance. The developed simulation framework encompasses a diverse range of areas, including isolated vehicle motion (such as acceleration, braking, and cornering) as well as complete lap time simulation (LapSim). These simulation scenarios have been carefully designed to incorporate crucial factors like weight transfer and aerodynamic map effects, effectively bridging the gap between simplified and advanced modelling approaches. Furthermore, the framework offers comprehensive tools for analysing suspension dynamics using both quarter and full-car models, facilitating the creation and evaluation of aerodynamic maps, and generating precise yaw moment diagrams. This wide array of simulation capabilities empowers engineers to select and utilize the specific features that align with their unique project requirements, thereby enabling more accurate and comprehensive analysis of vehicle performance. The simulation framework is developed using MATLAB, with each simulation sub-feature designed as a specific module format. It is important to note that the code for this framework is entirely self-developed, showcasing the author's expertise and dedication in creating a comprehensive and tailored simulation tool. This tool allows users to seamlessly interact by selecting the desired simulation scenario and defining the relevant inputs. Furthermore, this thesis aims to enhance engineers' understanding by presenting the fundamental principles and underlying dynamics of vehicle performance. The structure of the thesis is carefully designed to guide readers from more simplified concepts to more complex principles and dynamics, ensuring a progressive transfer of knowledge from one module to the next. Detailed explanations of the simulation algorithms and models are provided, along with example results for the baseline vehicle, allowing engineers to grasp the practical application of the presented concepts. By following the step-by-step progression of the thesis, readers are advised to gain a comprehensive understanding of the subject matter, empowering them to replicate the simulation tool, make necessary adjustments, and effectively evaluate vehicle performance. In conclusion, this master's thesis presents a robust and wide simulation framework for vehicle dynamics and performance analysis. With its comprehensive simulation capabilities and focus on enhancing engineers' knowledge, this research contributes to the advancement of vehicle design and optimization processes.	en
