Aircraft vibration can quickly build from an inconvenience for flight crew and passengers to an expensive problem for maintenance technicians. Left unchecked, excessive vibration can reduce the service life of the engine, instruments, and other mechanical components. Fast, accurate vibration analysis is important to determine the cause, so the problem can be fixed as quickly as possible
What’s Causing the Vibration
There are many reasons why vibrations occur. An imbalanced disc, for example, can cause periodic vibrations that are felt during each revolution. Some vibrations aren’t necessarily an indication of a problem, but a normal operating condition of mechanical systems. It’s important to know the difference between types of vibrations in order to avoid overlooking serious issues or making unnecessary repairs.
How Vibration Analysis Works
An electronic analyzer uses a sensor to measure vibration, checking for amplitude and frequency via AC signal. Modifiers are then used to fine-tune the signal, ensuring the user receives highly accurate readings on which to base any follow-on maintenance. Several types of surveys gauge vibration at varying states – including constant operational frequency and peak hold – for controlled testing and clear results. ACES analyzers provide some of the industry’s fastest and most accurate Vibration Analysis testing, for clear results in any environment.
The ACES Edge
Performing rapid and precise aircraft vibration testing can be difficult in a busy hangar or maintenance facility. Having the right instruments can often make all the difference. ACES Systems tools deliver speed and reliability in a compact package. The ACES line of Vibration and Performance Analyzers allow for high-end analysis of vibration, along with acoustics and balance (transient, rotor track, propeller) as well.
They’re engineered to deliver clear-cut results quickly, at speeds rivaled only by manufacturer test cells. Four channel data acquisition and SmartTach direct engine speed measurement provide unparalleled accuracy. Multiple speed inputs and sensor flexibility allow even more versatility for customized testing. ACES has combined powerful functionality with convenient 1GB memory storage and multiple USB port connectivity in the Viper II for a testing solution that makes data more accessible.
