According to the characters of the load stressed on the inner sleeve and outer sleeve of rolling bearing,the matching mode between rolling bearing and shaft,or hole could be chosen and divided into part load,circular load and oscillating load based on the mode of load acted on the sleeve.

Cause analysis and countermeasures of load fluctuations during valve switching of a domestic 300 MW unit;

Presents the load fluctuation characteristics of the turbogenerator unit,analyses the various reasons for the fluctuation and presents the solution

This paper presents the 3 types and characteristics of the load fluctuation of Y/GT-1701generating set,analyzes factors causing each type of fluctuation,and provides measures against fluctua-tions,which showed good result.

Taking account of the effect of climate factor on the annual peak load,a new forecasting model is applied to load forecasting,in which the peak load is divided into basic load and peak fluctuating load.

The paper e mphatically studies effects of fluctuating load for properties and life of diese l engine, discusses in detail effects of fluctuating load for scavenge process, formation of gas mixture, combustion process, governor work, wear of diesel engi ne and loss power of machinery, and puts forward some ways of improving working benefit of diesel engine.
