The Challenge
From the design stage, this control must lead to the most accurate sizing, i.e. sufficiently robust with respect to vibration fatigue but limiting oversizing, which would directly impact the cost of the installation.
In the case of an installation modification, the impact on the components vibration behavior must be limited while ensuring availability and cost control, but also anticipated to compensate for failures during commissioning and the resulting additional costs.
Finally, during operation, vibration phenomena that could lead to the unavailability of the function or to more serious consequences must be characterized, identified and remedial solutions proposed to regain the expected level of reliability.
