The main objective of this Master Thesis is to create an application that would automate the process of finding preferred double wishbone suspension kinematics while satisfying the constraints on suspension characteristics. This would in turn mean that students can spend less time on tasks which do not bring any new knowledge and more on optimizing the rest of suspension subsystem. Through internet search commercial and free suspension calculators with or without open-source code can be found. Commercial are characterised by use of a 3D suspension model while free calculators use 2D models with approximations or 3D models that are solved with the help of optimisation algorithms. However, none of them give insight to the mathematical models used for calculating suspension movement or characteristics what has been done in this master thesis for the 3D quarter suspension model and it is calculated directly, without iterations or use of the optimisation algorithms. Furthermore, currently there is no free suspension calculator that has implemented a module for suspension kinematics optimisation and the commercial ones either have this ability in beta stages (OptimumG) or complete optimisation model must be made from scratch (MSC Adams Car Module). Therefore, this is the first freely available tool, to the author’s best knowledge, with open-source code and accompanying explanations that implements suspension kinematics optimisation. Finally, success of free application largely depends on their ease of use, so a graphical user interface is developed. It is characterised by simple parameter modification of the current suspension, interactive visualization of the current 3D quarter suspension model, output of main suspension characteristics of the current suspension and with the ability to enter parameters for suspension kinematics optimisation. Finally, since sharing knowledge is common practice in Formula Student community, the source code is available at GitHub repository: https://github.com/brunomraz/FS-BMK
