Adaptive Damping for Trucks
Neuman, Ondřej ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis is concerned with designing a computational model of a commercial vehicle. In addition to that, a control algorithm for adaptive damping is presented. These two parts are connected into a closed loop and together they create an adaptive damping system. The primary task of the algorithm is to react on a vehicle load change. Vehicle model has the opportunity to create different driving scenarios, which are used to verify algorithm functionality. With the help of computational model and optimalization process, suitable damping characteristics are derived. An evaluation of vehicle comfort and driving safety is also presented.

Influence of standards changing on reliability of lightweight roof structures
Štěpánek, Petr ; Girgle, František ; Daněk, Petr ; Růžičková, Jana
This paper is intended to experts who work on the expert opinion for faults and breakdowns of lightweight roof load bearing structures. Changes of loading standards during the time play a fundamental role by redesigning of existing roof structures, especially of the lightweight structures. Significant differences are shown among the ČSN 730035 – 86, revise ČSN 730035 and ČSN EN 1991 in climatic loading (snow, wind). If any interventions into lightweight roof structures are planned it is necessary to pay attention to reliability of a load bearing structure. This paper describes some possibilities how to solve this problem.
