The Faculty of Mechanical Engineering, Ni?, Beogradska 14, 18000 Ni? Abstract . A high degree of accuracy in dimensioning and controlling the safety from destruction can be reached by measuring exploitation load of the vital elements of the construction. The choice of the adequate l oad spectrum is performed by introducing a number of representative spectrums for particular operating conditions, each of these having its probability of occurrence. The easiest way to solve the problem is to introduce the standardised load spectrums with the aim of forming the catalogues of the standardised load spectrums for representative mechanical systems. INTRODUCTION The requirements of the market are constantly growing plex with regard to productivity, quality and speed of mastering new products. Rapid development is the cause of the increase of designing and constructional tasks with even greater degree of complexity. The conventional "traditional" designing, based on empirical results and intuition, does not suffice for essful following of progress in other areas of human activity. In the engineering practice today, automat
