Acceleration Testing: Sine Burst Testing
For Static Pull and Centrifuge Testing
Acceleration Testing: Sine Burst Vibration Testing an Alternative to Static Acceleration Centrifuge Testing
Sine Burst (SB) Vibration Testing is used for strength testing of aerospace hardware and is applicable to structural testing. Sine Burst is an alternative to static pull and centrifuge tests. The test is particularly suitable for relatively stiff components or electronic boxes, instruments, or spacecraft.
The main advantage of the Sine Burst is that it is performed on a vibration system, the same vibration system that performs other tests such as random and/or sine sweep vibration and shock testing. Further, test article sizes can be much larger and heavier than in a Centrifuge. Performing all dynamic tests on the same vibration system reduces test costs and time.
Sine Burst Vibration Testing imposes a lower number of cycles compared with a sine dwell or sweep.
The NESC Publishes Best Practices for Use of Sine Burst Testing
|For more than two decades, sine burst testing has provided a method of strength testing for aerospace hardware that not only minimizes potential for damage to the test item, but can be performed on the shaker along with other tests to maximize efficiency. But with all testing comes potential risk. Mr. Daniel Kaufman, NESC Discipline Deputy for Loads and Dynamics, identifies top risks, such as unintended over test or erroneous calculations, and provides best practices to help mitigate those risks and take full advantage of what sine burst testing provides.|
