Movement in mils of displacement at various points in the horizontal direction along the side of several large integral compressors has been recorded. These movements have been compared using a fixed crank angle as a common reference point. The reference point used for this data collection is when the number one compressor is at the head end position. This information gives us a picture of how the engine frame is actually flexing when all internal components are in the same position. By comparing plots of movement along the side of the engine, we can observe the relative flexing of the frame at any point in the engine/compressor cycle. It was observed that a reverse bending of the frame is occurring on some types of engine frames which are known to have “typical” frame cracking in the same area that the reverse bending is taking place. Similar plots of movement are also compared between different engine types. The paper will explore the methods of collecting data, the comparison of data on individual engines, and a comparison between different engine frame types. Correlations are drawn between frame movement and cracks in the frame of some engine types. This work lays the foundation for future data collection and testing that could lead to modifications which could reduce frame cracks.
