Race car bonnet shape design based on flow analysis
Šnajdr, Petr ; Kvarda, Daniel (referee) ; Michalec, Michal (advisor)
The bachelor’s thesis deals with reducing aerodynamic drag of a pneumobile. The thesis summarizes knowledge in the field of vehicle aerodynamics and the principle of CFD simulations. The essence of the work is bonnet shape design of racing pneumobile Typhoon, developed at FME BUT, for lowest possible air resistance. CFD simulations are used to observe and analyse the influence of the bonnet shape on the aerodynamics properties. The designed shape solution of the bonnet significantly contributes to the reduction of aerodynamic drag compared to the existing bonnet. Thanks to this, the vehicle’s parameters are improved from maximum speed to the range. The acquired knowledge can also help in the further development of pneumobiles and in improving the setting of the computational model described in the work.

The Active Bonnet Hinge
Galda, Michal ; Růžička, Bronislav (referee) ; Brandejs, Jan (advisor)
This thesis deals with designing the construction of an active bonnet hinge, tuning the kinematics and appropriate proportioning of individual parts of the hinge. The thesis consists of two main parts – the first part is an analysis of the current state of knowledge and the second part presents a designing the construction. The active hinge should serve as a safety element in automobiles to minimize consequences of head injury suffered during the collision of a pedestrian with an automobile.

Study of Material Properties Influence on Pedestrian Head Impact on Bonnet
Coufal, Tomáš ; Svída, David (referee) ; Ramík, Pavel (advisor)
The thesis describes the complex of basic testing procedures conducted by Euro NCAP company with a view to the examination of pedestrian protection in accordance with EEVC WG 17 and topical instruments used at passenger vehicles for pedestrian protection. It includes a detailed procedure of the creation of an adult head impactor including its certification and the formation of its impact on the bonnet of the vehicle. It is specialized in the studies how material properties influence the size of HIC criterion.
