VC Vibration Curve Reference

Return the meaning and selection cautions of vibration-criterion curves for sensitive facilities.

Description

Vibration-criterion curves describe spectral vibration environments for sensitive activities.

Vibration-criterion curves describe spectral vibration environments for sensitive activities. Equipment requirements determine which criterion applies.^[1]

Return the meaning and selection cautions of vibration-criterion curves for sensitive facilities.

When to use VC Vibration Curve Reference

Use this tool to return the meaning and selection cautions of vibration-criterion curves for sensitive facilities.

Choose a supported reference topic, run an input-free reference with an empty object, or prepare the measured values and caller-supplied test records requested. Keep acoustic metrics, frequency, units and test conditions consistent.

How to use VC Vibration Curve Reference and understand its results

Choose a supported reference topic, run an input-free reference with an empty object, or prepare the measured values and caller-supplied test records requested. Keep acoustic metrics, frequency, units and test conditions consistent.
Enter topic using the field table and calculation rules, then run the tool.
Read source, statement, topic. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
topic	Reference topic to return.	string; one of "purpose", "selection", "caution"	Required

Choose an exact topic enum from the input table and run the lookup. The implementation selects a fixed local entry and returns source, statement and the selected topic. Matching is case-sensitive without trimming or free-text search.

result=stored entry for selected topic

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
source	Source used for the reference statement.	string
statement	Narrow reference statement for the selected topic.	string
topic	Selected reference topic.	string; one of "purpose", "selection", "caution"

{
  "input": {
    "topic": "purpose"
  },
  "output": {
    "source": "Gordon, Generic Vibration Criteria for Vibration-Sensitive Equipment",
    "statement": "VC curves classify one-third-octave vibration velocity environments for increasingly vibration-sensitive equipment and activities.",

  }
}

Limitations and assumptions

No vibration spectrum, vendor requirement or structural acceptance is assessed. The source is a stored bibliographic label, not a fetched document; statements are not refreshed at runtime.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods
