Field | Description |
---|---|
Name | The name assigned to the assembly in the System Tree Items table. |
Calculation model | The reliability prediction standard or model to use to compute the predicted failure rate of the assembly. Choices include all licensed models. As described in Model Selection, a lower-level assembly inherits the model selected for its parent assembly, but when the HRD5 model is selected, you can specify an override model, which child items also inherit. |
Temperature | The operating temperature of the assembly in degrees C. For more information, see Operating Temperature. |
Temperature delta | A temperature adjustment value in degrees C. This value is added to the operating temperature to get the ambient/environment/case temperature, depending on which is appropriate for the model selected. While this field is unavailable for the top-most assembly (system), it is available for all lower-level assemblies. |
Environment, HRD5 | The surroundings in which the assembly operates. This field appears when the HRD5 model is selected. For choices, see HRD5 Environments. Environment selections are inherited and overridden in the same manner as calculation model selections. For more information, see Model Selection. |
Environment, dormant | The surroundings in which the assembly is dormant. The choices are the same as those for Environment. |
Duty cycle | the percentage of time that the assembly is in an active state. For more information, see Duty Cycle. |
The subsequent fields specify whether assembly results are calculated or specified. For more information, see Calculation Data for Specifying Whether Assembly Results are Calculated or Specified. |
