Automating Mechanical FMEA Using Functional Models
نویسندگان
چکیده
This paper considers the application of functional modelling to the automated production of FMEAs for mechanical systems. We consider how a functional model can be generated algorithmically from the geometric and assembly data already present for a device in a CAD/CAM system. We present the functional model used for representing the mechanical system, and propose reasoning techniques that can be applied to the model in order to produce an FMEA.

An Automated Software FMEA
The concept of software failure mode and effects analysis (FMEA) has grown in attractiveness over recent years as a way of assessing the reliability of software. Like its hardware counterpart, software FMEA is immensely tedious for an engineer to perform, as well as being error-prone. This paper presents the implementation of a novel method for automating code-level software FMEA based on treat...

In this report presents our experience with automating parts of the FMEA process using a model checker. As the case study a minepump control system is used, that prevents flooding in a mineshaft
متن کاملOntology-based Transformation from an Extended Functional Model to Fmea
Conceptual design knowledge concerning with functions of products and phenomena unintended by designers is scattered around various forms such as the functional model and the FMEA sheet, which are dependent on engineering tasks. Aiming to promote sharing of such knowledge among designers, this paper proposes a knowledge transformation system from extended functional models to FMEA sheets based ...
متن کاملAn evaluation of failure modes and effects analysis generation method for conceptual design
Failure modes and effects analysis (FMEA) is used in the manufacturing industry to improve product quality and productivity. However, the traditional approach has many shortcomings that affect its effectiveness and limit its usefulness, especially in the early stages of design. Automating the FMEA report generation process seems to answer some of these problems, and there has been much past and...
متن کاملThe language of FMEA: on the effective use and reuse of FMEA data
Abstract Practical uses of Failure Modes and Effects Analysis (FMEA) range from the identification of potential design defects and safety hazards, to maintenance planning, diagnostics and Prognostics and Health Management (PHM). According to the broadly accepted standard for FMEA, MIL-STD-1629A, a successful FMEA is one that conducted in a timely manner, so that the results can be used to ident...
