We have performed strain gauge analysis on the support beams for steam carrying pipes and fixtures while debugging a power plant vibration issue. We needed to determine which supports were passing an expected 50,000 lb imbalance load to a control room structure. We have evaluated the bending stain in aluminum cast fan blades in their pre-production stage, and to perform strain testing as part of a failure analysis on a fan that would occasionally fly apart. We have measured dynamic strains to determine fatigue risks and to troubleshoot cracks forming is lightly loaded vacuum systems. We have used strain gages to create torque and weight sensors and measured many rotating systems using slip rings and telemetry instrumentation.
We use stain gauge testing and/or stain modeling and analysis in conjunction with our structural dynamics expertise to characterize all important pieces of the puzzle that come into play with dynamic strain issues (see Diagnostic Testing). We often use Finite Element Analysis to create dynamic models of portions of a complex vibration/thermal/strain issue. With our broad background in these relevant fields we are able to quickly and very efficiently characterize the issue and make recommendations.
