Opis:: With the worldwide competition so strong, it is essential for motor vehicles, regarding to power transmission, to have high reliability. The reliability design is one of the ways to reach this objective. The stage of design is the most important one in the life cycle of a power transmission. Reliability design, within the designing stage, correlates directly with the power transmission reliability. The problem of a practical power transmission, design has been solved by developing of a methodology suited to the purpose. The basis of the developed design represents a contemporary approach to designing, comprising the phases of conceptual, preliminary and detail designs, with applying of the reliability design method within these phases. Approach to technical system design, the algorithms of the developed vehicle design from market-users by reliability preliminary design, detailed reliability design to manufacturing, reliability block diagram are presented in the paper. The developed and applied methodology enables reliability design of the vehicle and its elements, with the objective of obtaining a reliable vehicle which is one of the main requirements for the competitiveness in the market of automotive vehicles.

Opis:: Permanent growth of the container shipbuilding has led to the need of research - developing activities with references to design and ship building process. The requirements for the container vessels have been modified and changed compared with the ships built in the eighties of the past century. The ships capacity have been increased up to and even above 10 000 twenty feet containers (TEU) with the service speed above 25 knots. For such a giant sea going vessels with the overall length above 300 meters and draught above 10 meters the ship hull resistance characteristics have been modified. Those conditions bring to the situation where the propulsion power for the seagoing ships reached 80 MW. The estimation of the main engine power relation in the preliminary design stage is the main aim of the paper. The problem is such important as in that stage the most important design decisions with relatively low investment costs are determined. Moreover, the preliminary design stage distinguishes that the designer possesses just a few design parameters given by the ship owner of the future vessel. That is why the correct choice of the main engine power is difficult to determine. Determination of the main propulsion power impacts the electric and heat energy amount and the production way of both energy forms. The main engine equation has been determined based on the container ship's parameters for the entire range of container vessels load capacity (TEU). The values of the design parameters have came from author 's data base for the contemporary container vessels.
