The mechanical interface has the characteristics of low shock and vibration, and is emphasized in the aerospace and ocean engineering fields. In this paper, a mechanical interface based on coupled cylindrical cam mechanisms is designed. It can achieve the expected functions, but there exist faults in some times. The fault modes and causes of the interface are firstly analyzed. Then a design approach based on Monte Carlo simulation is presented for analyzing and optimizing its reliability. According to the fault modes, the performance functions of the interface are established for obtaining the optimal scheme. A case is given to illustrate the proposed method. The simulation results and the prototype experiments prove that the optimization scheme effectively improves the reliability of the interface, and has better performance than the original one.

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.

In the current era, the role of smart devices is expanding every day. These devices depend on both software and hardware functions to produce the desired results. The success of such devices depends on a new design paradigm that considers reliability in virtually every aspect of the devices' software and hardware content. Design of a hardware system involves selection from numerous discrete choices among available component types based on cost, reliability, performance, weight, etc. Design of software systems involves the selection of the best choice from a stack of available choices with variable reliabilities and costs. We try to design an embedded system which optimizes the reliability in the perspective of cost or vice versa. An Integer Programming approach for simplified assumptions and an Evolutionary approach for the non-simplified case is proposed.
