Dynamic analyses

In the area of dynamic analyses, we perform calculations of modal properties of components and their responses to dynamic excitations. We often evaluate structure response to specific types of dynamic loading such as harmonic, seismic or transient. We also have experience with evaluation of random vibrations. Dynamic analyses could also include problems of fluid-structure interaction (FSI analysis), that may lead to self-excited oscillation (flutter). Based on these analyses, we can predict lifetime of structures considering the dynamic effects. Analyses can also support design modifications to reduce vibration and extend the service time.

- Modal analyses (natural frequency and mode shape calculation)

- Harmonic analyses (calculation of steady-state response to a harmonic excitation)

- Random vibration analyses (calculation of response to a random loading)

- Qualification of structure for seismic loadings (according to the ASME Code or Eurocode)

- Modeling of interaction between fluid and structure (FSI analyses, flutter)

- Transient dynamic analyses (simulation of component response during transient states such as startup, shutdown or non-stationary event)

- Optimization (structure tuning to reduce vibration, improve dynamic stability, reduce cost…)

- Assessment of a vibration impact to structure failure

- Rotordynamics

- Concept of the existing machinery repair to reduce vibration and eliminate failure

- Identification of vibration sources

- Comparison of different designs (different concepts, manufacturing technologies, materials…)

- Time savings

- We can help you to meet the schedule

- Identification of potential issues during the design phase (elimination of operational problems and warranty claims)

- Cost savings

- Elimination of necessity to build a prototype (product behavior can be tested using numerical models)

- Lowering of operational failure risk and thus reduction of costs related to solving the failures

- Competitive advantages

- High quality engineering analyses reduce the potential of products to fail (faulty product harms the reputation of the manufacturer)

- Our technical report can help you to demonstrate to your customer compliance with the requirements on the product
