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 load 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 more complex 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 successful following of progress in other areas of human activity. In the engineering practice today, automatised designing is an imperative, which is caused by the use of computers in the process of developing a product. New tools for overcoming the flaws of the classical approach can be classified under the term CIM- Computer Integrated Manufacturing- which defines the integrated flow of all information both within and outside the company. CIM consists of modules such as CAD (Computer Aided Design), CAM (Computer Aided Manufacturing), CAPP (Computer Aided Process Planning), CAQ (Computer Aided Quality) etc. The utilities and tools of CAD technology can be most widely applied in aut
