Vertical Dynamic Balancing Systems – Isolating Repeatability Issues in Challenging Applications
ARP8911
This new Aerospace Recommended Practice will serve as a practical resource that offers guidance to both the machine operator and Process Engineer for isolating the source(s) of non-repeatability in measured unbalance data. The content of this standard addresses:
• Vertical Dynamic Machine Capability to achieve the specified unbalance tolerances and repeat within those tolerances
• Tooling Capability to repeat within the specified unbalance tolerances
• Rotor characteristics that may preclude repeating within the required unbalance tolerances.
Rationale: The objective of this document is to present a recommended method for successful demonstration and validation of a new vertical dynamic balancing process prior to approval for production use. This Aerospace Recommended Practice will be useful to both Process Engineers and Machine Operators.
