This paper presents a case study for the strength demonstration of a railway wagon welded node using the probability approach. The design variables were taken from the existing standardization for railway vehicles. The fatigue damage summation method for proving the satisfactory service life as well as the Goodman diagram method for verification of the unlimited service life was used for the node examination. The probability estimation was made using the Monte Carlo SBRA method with the help of the Anthill software. and Obsahuje seznam literatury
Experimental measurement is performed on a simple fibre-mass system: a moving mass coupled with the frame by a fibre. Dynamic response of the mass is measured. The same system is numerically investigated by means of a simple multibody model. The influence of the model parameters on the coincidence of results of experimental measurements and of simulations are evaluated. The simulations aim is to create a phenomenological model of a fibre, which will be utilizable in fibre modelling in the case of more complicated mechanical or mechatronic systems. and Obsahuje seznam literatury
