Track center detection is a key step of the Smart car traveling along the track, and its accurate detection provides necessary information for direction and speed controlling. This paper proposes a simple and effective position prediction based method for detecting the track center of the Smart car, which consists of the following four steps: (1) Initialization; (2) Position prediction; (3) Position...
Fault tree analysis (FTA) is a top-down approach for failure analysis, starting with a potential undesirable event called a TOP event, and then determining all the ways it can happen. FTA is the most commonly used technique for causal analysis in risk and reliability studies. Mask stage an important part of lithography. In this paper, Fault Tree of the mask stage is built with “Mask stage doesn't...
Failure Mode, Effects and Criticality Analysis (FMECA) is used widely in engineering practices such as aerospace, medical facilities, naval vessels and shipping, which improves the reliability and safety of the products significantly. It can eliminate potential failures, errors and problems from design, system and process. To overcome the drawback in the traditional Risk Priority Number (RPN) [1],...
Maintainability analysis method combined with FMECA and FTA is proposed for the failure analysis of a type of diesel engine combustion system. Failure modes and cause analysis for this type of diesel engine combustion system are identified, and the hazard is analyzed. Finally, the real failure situation of this diesel engine is presented to validate the analysis results from the proposed method, which...
Failure Modes and Effects Analysis (FMEA) is an effective technique for identifying and eliminating possible failures. FMEA has been widely used in the manufacturing industry and in various phases of the life cycle of a product. The aim of FMEA is to ensure high quality and reliability. Design FMEA (DFMEA) is used to identify and analyze potential failure modes and their associated causes for product...
