NPRP: Non-electronic Parts Reliability Prediction

RPA > Mechanical Predictions contains the NSWC-11 standard for Non-Electronic Parts. The following sections appear:

  • Environmental conditions: It contains the “Operating Temperature”, the “Rated Temperature”, and the “Ambient Temperature”

  • Component parameters: The parameters required to be filled

  • Schematic (if any)

By selecting a specific component, the parameters change accordingly. Furthermore, Robin provides, for each parameter:

  • The units which the engineer should use when entering the parameter value, on the right side

  • (If necessary) Additional information to clarify the meaning of the parameter or usual values, on the left side

When entering all the necessary parameters, the user can compute the failure rate and the following data is obtained:

  • Failure rate in inverse Operating Hours

  • Formula applied to obtain the failure rate

  • Failure rate chart depending on the temperature
