MATHEMATICAL MODELLING OF ACCUMULATION OF DAMAGES OF THE DESIGN AT THE SET LOADING MODE
Settlement dependences which consider distribution of the maximum values of tension are simulated and checked and contain parameters of casual process. Besides, parameters of the curve fatigue describing regularity of accumulation of damages to a design and loss of its working capacity at the set loading mode are their part. All calculations by definition of durability of system are carried out if to consider distribution of amplitudes load when integrated function is defined by Rayleigh´s distribution.The durability of system can be defined if to consider distribution of the maximum (extreme) values of tension in the limiting design element at action on it casual process of loading.As output parameter loading, the considered mechanical system operating on – the bearing design - the main beam of the metallurgical bridge crane is considered. The limit of loading is defined by the mode of loading and rejections of strength characteristics of material of elements of designs of system.
