COMPARISON OF FREE END AMPLITUDE _
There are now several sets of test and calculated data on free end amplitude taken on both the 13 x 11 and 13 x 12 replacement crankshafts at rated con-ditions. TDI's torstograph data shows three to five amplitudes of selected orders and the corresponding SRSS value. SWEC test report shows a full array of the free end amplitudes, and its corresponding true sum results (0.69 degree). The experimental spread was 0.55 to 0.69 degree when
.1 several recordings were studied.

" Shop Test for EDOK-ETER. SM-74038. overall per meter Fo-the 13 x 11 shaft, the SWEC as well as TDI test data shows around 30 -
40% higher 4.0 order amplitude than that of 13 x 12 shaft. This irdicates that the 13 x 12 shaft stress level is indeed significaatly reducec. For the 13 x 12 shaft TORVAP C true sum amplitude checks well within tha experi mental spread of the SWEC test.
In addition, TORVAP SRSS result checks within a few percent of the test data furnished by either TDI or SWEu.
