18 Results <strong>of</strong> Sensitivity Study (1/4) • Overall, the assembly in C-2 has the best stress distribution; while the assembly in C-3 has the highest stress regions. • As can be seen in the next slide for C-1 and C-2, decreasing the interference at Int-2 (i.e. at lower interface between bearing housing and cooling sleeve) tends to distribute the stress better and also reduces stresses in bearing housing and sleeve. This is also demonstrated by comparing C-3 to C-1. • As can be seen in the next slide for C-1 and C-3, increasing the interference at Int-3 (i.e. at interface between cooling sleeve and bearing sleeve) tends to increase stresses, especially in bearing housing and cooling sleeve. This can also be observed by comparing C-4 to C-2. • Therefore, reducing the initial interferences at Int-2 and Int-3 will lower the stresses in the assembly including the welds. • These stress results can then be used in the further structural integrity and component fatigue life assessments.
