Vehicle Bumstops and Reboundstops
 Mikeš, Josef ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The aim of this master’s thesis is to create a mathematical description of the functioning of vehicle suspension stops. There are two basic types of suspension stops, mechanical and hydraulic. The mechanical one accumulates energy at the end of the suspension stroke, The hydraulic one converts the residual energy into heat. In order to understand the problem of stops, research on the function and current trends in the design of stops is carried out in the first part of the thesis. This work includes an investigation of the effect of stop positioning and stop characteristics on vehicle behaviour. The characterization was investigated by changing of the force ramp intensity and adjusting the global stiffness of the stops. By varying the onset of action of the hydraulic and mechanical stops, there is a position in which the driving characteristics of the car are improved. It is advantageous to use this position in the design of the stops. The result of comparing the different options is a design of suspension stops for a particular vehicle. Due to the action of the hydraulic stop, the damping oil is heated, but by checking the dissipated energy it can be concluded that this heating is quite minimal.
