Finite Element Analysis or FEA is an established numerical simulation technique to validate the product under certain performances. Per need; various product performances are broken in to a series of analyses…
To start with, Static analysis reveals baseline performances of each component of the product, with fairly good insights in terms of stresses, displacements, safety factor and many more. Most of the rectification workouts are done with this study using established thumb rules and domain specific experience. Linear or non linear static studies can be used depending on component geometry, and material. Static studies can be carried out on various component forms like truss, beam, shell, welded; and also assemblies.
Thermal Analysis, both in steady and transient scenarios, gives insights on the thermal management on products like, enclosures, PCBs, and almost any product having heat generating components. This analysis can be coupled with static and dynamic analysis for seeking better thermal- structural performances.
Going in depth performances under stringent dynamic environments; results from static studies are coupled to Dynamic Analysis for individual components. The nature of loading, whether it is time dependent, random, harmonic; performance insights are drawn in a more better way. To the extent, wind, earthquake, loads can also be studied using "Response Spectrum Analysis". Frequency Analysis is used as a precursor for extensive Dynamic Studies. By extracting the relevant modes and mass participations, Frequency Analysis, shows whether the component behavior is good enough to proceed further for detailed Dynamic Analysis.
To seek the extent to which components can serve the critical functions in the assemblies; Fatigue Analysis is used. Here, the percentage damage, load factor, life in terms of no. of operational cycles can be estimated.
Buckling Analysis is used for taller structures made of trusses, composite columns, extruded sections. For a given loading patterns, arrived load factor for individual buckling modes can predict structures performance.
Drop tests are more useful in deciding the packaging of small multi stack bottles, larger containers, and product enclosures; looking at the handling and transportation scenarios. Depending on the nature of material intended, non linear and linear drop tests can be carried out. As a result, the nature of wear and its occupying volume on the component can be estimated.
Pressure Vessel Design, accepts results of static and dynamic analyses carried out on typically boilers and Heat Exchanger shells. Any nozzle interaction to the main shell and linearization of all sort of stresses for further evaluation can be handled in this analysis.
