Derisking – Diagnosis and solutions
In order to avoid mechanical problems (noise, vibration, CFD, shock, static load, thermal), the development of a product must meet specific requirements from the preliminary project stage. CEVAA supports manufacturers in this derisking stage.
What is industrial derisking?
Derisking in product development, particularly when it comes to mechanical issues, consists of a set of strategies and actions aimed at anticipating, evaluating and reducing the risks associated with the design, manufacture and use of a product.
Derisking multiple problems by numerical simulation
Simulation is a great derisking tool that allows you to intervene as early as possible in the development phase of a product, as soon as a virtual prototype is available.
Calculations of natural modes, calculations of vibration frequency response functions or acoustic pressure will allow you to compare the product’s response with the requirements of the specifications.
Our team of engineers works on issues of noise, vibration and static resistance, shock and impact resistance, or even the acoustic behavior of seals, etc.
Examples of digital derisking
- Study of the suspension of an electric motor (calculation of the reception stiffnesses, iteration on the stiffnesses of the silentblocs in the different axes)
- Calculation of the acoustic insulation performance of a deck, a crossing (calculation of the insertion loss in a small cabin)
- Calculation of the earthquake resistance of a nuclear power plant crossing
Diagnosis of vibro-acoustic problems and solutions
When the acoustics and vibration behavior of a product are not an integral part of the specifications or when an adaptation of an existing product is carried out without a digital derisking phase, the risks of problems occurring are intrinsically increased.
This can become critical, for example when a noise problem appears and prevents the marketing of a product that is too noisy or when a vibration resonance phenomenon leads to a mechanical failure. However, all is not lost!
A diagnosis of the problem will make it possible to observe the phenomenon, quantify it and explain its causes. The CEVAA laboratory has the measurement means and skills necessary for this diagnosis.
The use of digital simulation makes it possible, when useful, to validate hypotheses posed during testing and to analyze the causes of the problem in more detail.
Our teams are able to support our customers until the problem resolution phase by sizing technical solutions adapted to the product process and the economic context.
Sizing can be done by digital optimization of the virtual prototype or by modeling solutions in principle on a physical prototype.
