Forced Vibration of Bus Bodyworks and Estimates of Their Fatigue Damage

Popis výsledku v původním jazyce

Driving a road vehicle on uneven roads causes its bodywork to vibrate. The vibration of the bodywork can result in fatigue damage of critical bodywork nodes. In the case of buses (trolleybuses, battery electric buses), the critical structural nodes are welds of thin-walled profiles, most often corners of openings for doors and windows. The fatigue properties of critical structural nodes are expressed by S-N lines. S-N lines can be determined in advance by performing laboratory fatigue tests. The time series data of stresses in the bodywork have the character of a random process. These stresses can only be determined with sufficient accuracy by strain gauge measurements, either while the vehicle is running on real tracks or on a proving ground. Fatigue damage can then be estimated using the appropriatefatigue damage accumulation hypothesis. The paper demonstrates a case study that uses data from the authors’ practical cooperation with bus producers.
