The detailed mechanical Failure Modes, Effects and Diagnostic Analysis (FMEDA) is a technique used to evaluate the reliability of a given mechanical product based on the detailed mechanical drawings of the assembly
The results of a FMEDA are a set of failure rates that can be used to determine the probability of failure, and the Safe Failure Fraction (SFF) needed for a given SIL.
Typically the mechanical FMEDA is supported by a design / construction FMEA to prove the robustness against sistematic design faults.
The outcome of this service is a detailed mechanical FMEDA / FMEA report that meets all IEC requirements for such a document.
- exida SILcal v.9
- IQ FMEA
SILcal is an analysis tool wich shall help and support hardware designers of safety-related systems to:
- Carry out a detailed Failure Modes, Effects and Diagnostics Analysis (FMEDA) according to IEC 61508 with:
- traceable failure rates
- traceable distribution of the failure rates for the different failure modes;
- concentrate on the analysis work by offloadinf the development team from searching and selecting activities for failure rates and failure modes
