Sandwich Insert Design of the Formula Student Monocoque
Velfl, Tomáš ; Šplíchal, Jan (referee) ; Löffelmann, František (advisor)
The bachelor thesis is devoted to the insert joints and wheel suspension attachments on the racing frame of a Formula Student vehicle. First, research was done to obtain the necessary knowledge on the subject. Then the external loads stressing the joints were experimentally and computationally determined. Before starting the actual design of the attachments, the effect of introducing local loads into the sandwich structure of the monocoque was investigated, firstly on small calibration samples. The first phase of testing was to verify the failure mechanisms, the interaction between the different components of the composite sandwich and to test different attachment designs using different materials. Based on the data obtained, the material libraries were refined, and computational models were developed and extended by parametrization. Thus, in the next step, the final designs of the individual suspension points meeting the predetermined objectives were iteratively created. During validation tests, the functionality of the design and sufficient oversizing were demonstrated. Technologies such as CT scanning were also used. The results were evaluated to determine further testing options and further improvements to the current solution.
