Investigation of TESCOM Driveshaft Assembly Failure

Abstract

This report summarizes the investigation into the failure of the driveshaft assembly during TESCOM compressor testing. The driveshaft assembly and compressor were disassembled and inspected, and data recorded during testing was played back and analyzed. This report provides details of the inspection and analysis. Results indicate that the driveshaft assembly failed as a result of an unpredicted shaft natural frequency in the operating range of the compressor. Recommendations are provided to reduce the possibility of such failures during future test programs.
