    Nagode, Marko ; Fajdiga, Matija
    One of the major problems that has to be solved to carry out the evaluation of dimensional suitability and reliability of dynamically loaded designs is the prediction of possible loading states to ... which a structure should be exposed during exploitation. To determine random loading states it is usually necessary to carry out test-evaluate phase of a design process, which is often time-consuming and expensive because of complex operating conditions. Because the time needed for measurements is mainly influenced by a large number of experiments, the main objective of the research was to answer the question of whether it is possible by experiment design methods, to form a sample of possible loading states. The so formed sample should be based on a small number of experiments and, despite its small range should make us possible to predict reliability with a sufficiently small statistical risk. To do this, various Taguchi methods of experiment design were tested. The investigation showed that especially in the case of complex operating conditions it is possible to considerably reduce the time needed to carry out the test-evaluate phase of developing process. In the particular case it was possible to reduce the original 864 measurements to altogether 96, whereby the scatter of the results obtained by the classical and Taguchi approach to matrix-of-experiment construction was very small.
