Optimální dimenzování s ohledem na spolehlivost a náklady

Original language description

Load carrying components must be dimensioned so as to guarantee safe and reliable function during the demanded time, and for reasonable price. The paper deals with the costs for ensuring the reliability and lifetime, in relationship to dimensioning. Larger cross-section means higher manufacturing costs, but also lower stresses, lower probability of failure and the related costs, or longer fatigue life and lower costs per unit time of operation. The paper gives the formulae for costs calculation and shows how to optimise the cross-section size in order to obtain the minimum total costs. The stress-strength interference theory of reliability is used for sudden failures, and the Woehler relationship ?load ? time to failure? for structures with fatigue orother deterioration. The typical development of total costs with the cross-section size is shown for several important cases.
