Změny spolehlivostních charakteristik v závislosti na stáří vozidlel

Abstract

The topic of this diploma thesis is to study the changes of reliability characteristics depending on vehicles age. Two types of buses („Karosa B952“ and „Solaris Urbino 12”, both of them 5, 7 and 9 years of age) coming from „Ostrava – Transport, joint-stock company“, were used for monitoring these changes. In the first part of this thesis, the structure of fleet is described, together with fundamental parameters of some representative vehicles. In the next part, calculation methods for reliability evaluation are presented. These calculation methods are used to evaluate the reliability characteristics and the maintenance expenses using the service experimental data. In the final part, the found out reliability characteristics together with maintenance expenses are discussed from the technical and economical point of view.
