We have completed dozens of rail car coupling and over the road stress analysis projects for monocoque steel frames used to support cooling compressors and other refrigeration equipment. Analyses considered high-cycle fatigue and dynamic stresses from a linear response spectrum analysis. Steel assemblies examined to comply with AISC recommended limits.
These analyses not only helped ensure that the frames performed through their expected life-cycle, but they also allowed Thermo King to reduce material cost via structural optimization. Our client was able to realize the value of an efficient structure made possible by finite-element analysis.
Up to 25% material savings was realized after performing Power Spectral Density (PSD) response spectrum analysis.
