Turboexpanders and other rotating equipment have components that are subject to axial bending, and torsional stiffness during normal operation. These operating properties can cause instability and vibration and can lead to premature failure if the components are not engineered properly. By using FEA techniques and specialized software, engineers can analyze the operating modes to make sure your equipment will operate with a high degree of stability and durability.
FEA is the practical application of the finite element method (FEM), which is a numerical technique for finding approximate solutions of partial differential equations (PDE) as well as of integral equations. FEA is particularly useful to engineers who need to solve complex elasticity and structural analysis problems.
