Structural analysis

A static structural analysis determines the displacements, stresses, strains, and forces in structures or components caused by external loads. Steady loading and response conditions are assumed; that is, the loads and the structure’s response are assumed to vary slowly with respect to time. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, aircraft and ships. Structural analysis employs the fields of applied mechanics, materials science and applied mathematics to compute a structure’s deformations, internal forces, stresses, support reactions, accelerations, and stability. The results of the analysis are used to verify a structure’s fitness for use, often precluding physical tests. Structural analysis is thus a key part of the engineering design of structures.

Modal analysis

Modal analysis is the study of the dynamic properties of systems in the frequency domain. Modal analysis helps to determine the vibration characteristics (natural frequencies and mode shapes) of a mechanical structure or component, showing the movement of different parts of the structure under dynamic loading conditions. The natural frequencies and mode shapes are important parameters in the design of a structure for dynamic loading conditions. In structural engineering, modal analysis uses the overall mass and stiffness of a structure to find the various periods at which it will naturally resonate. These periods of vibration are very important to note, as it is imperative that the  natural frequency does not match the excitation frequency of the component. If the excitation frequency matches with the a structure’s natural frequency, the structure may continue to resonate and experience structural damage.

Fluid structure interaction

Fluid–structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. FSI provides deep insight into how fluid forces can move and deform structures. Fluid–structure interactions can be stable or oscillatory. Fluid–structure interactions are a crucial consideration in the design of many engineering systems. Failing to consider the effects of oscillatory interactions can be catastrophic, especially in structures comprising materials susceptible to fatigue. We at turbo labs offer FSI analysis methods for turbo components and general applications
