If a machine experiences a problem because of an unexpected resonant frequency, high local flexibility, a weak element in the system, an unexpectedly high dynamic load, or excessive sensitivity to known dynamic loads, structural failure may occur.
Finite element (FE) analysis helps find correction factors that make more cost-effective, simplified analyses as accurate as possible. This approach provides flexibility factors for reinforced piping joints, adjustment factors for calculating forces transmitted by reciprocating compressors to their foundations, and the rotor stiffening effect of interference fits in turbomachines.
Southwest Research Institute (SwRI) engineers complement their field problem solving and failure analyses services with finite element analysis to diagnose causes and develop design solutions.
Structural Integrity Assessment
SwRI applies finite element methods to evaluate structural dynamic characteristics of skid-mounted centrifugal and reciprocating compressors used for gas compression.
