A fourlobe pressure dam bearing which is
produced by cutting two pressure dams on the upper two lobes and
two relieftracks on the lower two lobes of an ordinary fourlobe
bearing is found to be more stable than a conventional fourlobe
bearing. In this paper a fourlobe pressure dam bearing supporting
rigid and flexible rotors is analytically investigated to determine its
performance when LD ratio is varied in the range 0.75 to 1.5. The
static and dynamic characteristics are studied at various LD ratios.
The results show that the stability of a fourlobe pressure dam
bearing increases with decrease in LD ratios both for rigid as well as
flexible rotors.
