RISK PROBABILITY NUMBER RPN SOFTWARE
The reliability software tool used to analyze this study is Reliasoft's Xfmea Version 5.1.1. The WTs situated in high windy region have different kinds of modes of failure than the low wind region. The FMECA was carried out for Wind Turbine System (WTS) and its sub assemblies to check the design reliability of twenty numbers of 250 kW WTs, located in Muppandal, India, over the span of 15 years. The WTs have several failure modes which are correlated to each other because of the common failure mechanisms behind them. This paper presents the results for the Failure Modes Effects and criticality Analysis (FMECA) performed for the Wind turbines (WT) located in a high uncertain wind environment. Risk priority Number (RPN) is basically used to figure out which braking component is at the risk offailure and requires more surveillance. FMEA procedure is used in this paper to find out different failure modes, itseffects, causes, occurrence and different prevention ways for various components in a braking system of an All-terrain vehicle. An efficacious procedure of failure analysis is the Design Failure Mode and effect Analysis. This involves the prediction of the failure modes in the designing stage.
Since the safety of the operator is imperative in such events so there is a need of a safe and infallible braking system.
RISK PROBABILITY NUMBER RPN SERIES
BAJA SAE entails designing, Manufacturing and validation of an ATV which participates in series of events for 3 days which tests the agility of the buggy. BAJASAE is an ATV fabricating event organised by Society of automotive engineers (SAE), India for engineering undergraduates. By conducting a literature review of the development and trending of FMEA research, it provided new research opportunities to proved the FMEA issues reviewed in this paper.ĪTV is an all-terrain vehicle which can basically run on almost all types of topographies and moves on four low pressure tires with a seat bestrode by the Driver. There were eight research questions that could be considered from the results. This paper provided the critical analysis about the point of weakness FMEA based on document FMEA, and also limitation FMEA based on risk management process. The limitation FMEA was due to the subjectivity and caused inconsistent results. Data collection and identification stage was carried out by the selected papers for further analysis and synthesis. As a result, 32 papers were obtained in the selection stage according to the criteria used and review based on quality content. A systematic literature review methodology was conducted in order to review FMEA. The purpose of this paper is to provide a resume and critical analysis of previous research that discussed the development and limitation of FMEA. Several studies criticized the FMEA limitation or weakness of using this method. FMEA also was suitable for assessing risk in information technology or systems aspect. The proper using of FMEA method is proven to reduce the cycle of warranty costs and will certainly cost less to prevent than to fix the problems that have already occurred.
