our approach aimed at maximizing productivity & efficiency.
vibration analysis
The FE vibration analysis allows the prediction at the early design stage of potential issues with high vibration caused by a resonance frequency or high harmonic excitation. Simulea offers detailed calculations of natural frequencies and mode shapes starting from single components to complex assemblies. In addition to modal analysis, a forced vibration analysis can be conducted to predict the response of a structure to various types of excitations and loading. The Forced vibration analysis gives the ability to predict the sustained dynamic behaviour of structures, thus helping to verify whether or not the design will successfully overcome resonance, fatigue, and other harmful effects of forced vibrations.
Knowing the vibration characteristics of the structure, our engineers can conduct optimisation of the design to shift natural frequencies to safe frequency regions, reduce vibration stresses and deformation. We are using the best available package on the market for topology and topography optimisation, OptiStruct.
List of typical forced vibration analysis:
- Harmonic analysis
- Random vibration analysis
- Response spectrum analysis
- Full transient dynamic analysis
Explicit Dynamic Analysis
An Explicit Dynamic Analysis is well suited to products that needs to sustain severe loading conditions like impact, crash, blast or excessive plastic deformation. The design of such products can be greatly improved with the use of FE explicit analysis. Simulea engineers have wide experience in many advanced analysis tools like Ansys, Abaqus, LS-Dyna and HyperWorks to accurately predict design response to severe loadings. Using computational analysis to predict design response is especially important when it is too expensive or impossible to perform physical testing. The design can be verified considering many loading scenarios, thus improving its performance, quality, and safety.
An FE explicit analysis allows comprehensive, automated optimisation of the design to meet product requirements. Simulea is using best optimisation software available on the CAE market, OptiStruct. Our engineers possess the knowledge to optimise the design to meet static and dynamic strength targets quickly and efficiently.
