【Abstract】 The distribution of tre bearing loads of the domestic 200MW turbine generator set, which depends on their relative positions,have been studied under different supporting conditions. An iterative method has been developed to calculate all of the bearing loads, which takes the structural static indetermination and nonlinearities of the oil film forces into consideration. Variations of the bearing relative positions and their influence on the stability of the rotor-bearing system, have also been discussed.更多还原
