MOLA Force Limiting and Notching for Random Vibration Testing

WebApr 25, 2024 · In Sine or Random control, notching and limiting is a common technique used to limit the response level within a certain frequency range. Previously, users were not able to limit the SRS spectrum level within a certain frequency range for any response channel. Predictive Notching provides a limiting function for any input channel. WebNOTE Notching is a general accepted practice in vibration testing to avoid over testing of the item under test. Implementation of notching is subject to customer approval and … Webany notching during a vibration test, regardless of method, should be based on the force-limiting principles and methods described in NASA-HDBK-7004C [1]. With this methodology for a random vibration test, the applicable test acceleration spectral density (ASD) is reduced as needed to keep the crystal bynum
