COMPUTE DYNAMIC STIFFNESS¶
Computes dynamic stiffness from physical-test frequency-response data by pairing force and displacement (or acceleration) signals and deriving the complex stiffness spectrum. Use this worker when NVH test results need to be processed into dynamic stiffness curves and optionally stored as a new physical-test record in the platform.
When to use¶
Tagged: dynamic_stiffness, frequency_response, frf, nvh, physical_test, stiffness_curve.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Physicaltest | input_pt_id | remote_lookup | — | One or more existing physical-test records whose raw NVH/FRF channel data will be used as the input signals for dynamic-stiffness computation; leave empty only if supplying data via a mapping database instead. | |
| Mapping Database | input_database_id | remote_lookup | — | One or more mapping-database records that define how raw signal channels are mapped to force/displacement roles; required when channel naming conventions differ from the default layout. | |
| Create New Test | create_new_test | select | no | Controls whether the computed dynamic-stiffness result is saved as a new physical-test record (‘yes’) or merged into the source test (‘no’); defaults to ‘no’. | |
| Test Post-fix | new_test_name | text | no-name | String suffix appended to the auto-generated name of the new physical-test record when ‘Create New Test’ is ‘yes’; ignored when create_new_test is ‘no’ (default: ‘no-name’). |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| Physical test | physicaltest_id | integer | Integer platform ID of the physical-test record that holds the computed dynamic-stiffness curves; points to either the newly created record or the updated source record depending on the create_new_test setting. |
