Impact of CG on Post Crash Vehicle Movement
Kunovský, Martin ; Bradáč, Albert (referee) ; Semela, Marek (advisor)
This diploma thesis analyses the influence of the change to the vehicle’s center of gravity on its after-impact movement. The theoretical part of the thesis describes the basic methods which are used in investigation of the transverse, lengthwise and height position of center of gravity or the influence of center of gravity’s vehicle position to its stability and handling. Next part of the thesis deals with basic division of the road accidents and briefly describes the methods used in its analysis. Problematic maneuvers and everyday road traffic situations are stated in this thesis. Chosen situations were simulated in Virtual CRASH and PC crash programmes. Influence of the transverse, lengthwise and height position of center of gravity was investigated in these programmes with regards to the after-impact behaviour of vehicle. The obtained results were evaluated in the final chapter.

Crash test – a rail vehicle with a bus
Zębala, Jakub ; Ciępka, Piotr
The paper presents the results of a crash test in which a rail unit consisting of an SM 42-611 diesel locomotive and a 411 S snow plough collided with a Jelcz M11 bus. The presented results encompass: the collision velocity of the vehicles, and EES parameter of the bus, as well as simulation of the collision and the post-collision movement of the vehicles, carried out using the PC-Crash program.
