Referencing external data sources
The following describes how components from external sources can be referenced in a REXS model/REXS file. This enables more modular construction of REXS models.
Referencing components in a REXS model
Similar to referencing GDE files or Klingelnberg neutral data files, a "placeholder" component is initially required in the REXS model. The REXS model uses this "placeholder" component in relations with other components and can reference a component in an external data source (database or another REXS model) using the referenced_component_id attribute. The referenced_component_id must be unique in the data source(s). Model-specific parameters (e.g., POSE, orientation of the reference side/cone tip, direction of axial force absorption, etc.) are specified in the placeholder component. If an attribute is specified in the placeholder component and the database component, the value in the placeholder component takes precedence. Placeholder subcomponents (e.g. rolling elements) are not allowed.
The external data source to be used can be identified via the data_source attribute. The data source does not necessarily need to be explicitly specified; however, the list of potential data sources/databases must be stored in the application that the REXS model imports in advance.
Figure 9. Example: Referencing rolling bearings from an external REXS file
Two of the four rolling bearings in the REXS model are referenced from an external file.
Figure 10. Example: Referencing a shaft component, including shaft sections and material data, from an external REXS file
(1) Data from the external file is "injected" into the Welle [3] "placeholder" shaft component.
(2) The path to the external file is specified in the data_source attribute.
(3) The referenced_component_id attribute includes the ID of the component to be used in the external file.
(4) Model-specific attributes (such as the vectors for positioning in this example) are specified in the "placeholder" component, not taken from the external file.
(5) The components in the external file can in turn include sub-components (in this case, two shaft sections and a component for the material data).
(6) The relations between the shaft and its sub-components are also specified in the external file.
REXS database files
A REXS Database can be stored in a separate REXS files. To do so, the REXS file contains a list of "main components" as well as any sub-components and associated relations for each main component.
Table 6. Components in REXS database files
Permissible main components | Permissible sub-components |
|---|---|
Materials (material) | none |
Woehler S-N curves (sn_curve) | none |
Lubricants (lubricant) | none |
Tools (bevel_gear_tool, cutter_wheel_tool, rack_shaped_tool, worm_grinding_disc_tool, worm_wheel_hob_tool, zero_degree_grinding_disk_tool) | none |
Rolling bearings (rolling_bearing_with_catalog_geometry, rolling_bearing_with_detailed_geometry) | rolling_bearing_row, rolling_element, material, lubricant, rolling_element_contact |
Shafts (shaft) | |
