Analysis on Operating Clearance of Matched Single Row Tapered Roller Bearings for Wind Turbine Main Shaft

南方能源建设
[Introduction] The main shafting structure with double supports of single row tapered roller bearings has been widely used in wind turbines, and determining the appropriate bearing operating clearance is crucial for the reliable operation of bearings and

Strain-based fatigue analysis of wheelchairs on a double roller fatigue machine.

Journal of rehabilitation research and development, 1996
Results are presented from an experimental program that recorded the outputs of strain gages mounted on two wheelchair frames (one manual, one power) as the wheelchairs were run on a double roller fatigue machine. Rectangular strain gage rosettes were attached to the frames near the cross tube center pin and on the side frame behind a front caster ...

Study nonlinear vibration characteristics of vibrating roller-subgrade coupled system in the initial and middle stages of vibratory compaction

Journal of Low Frequency Noise, Vibration and Active Control
The vibratory roller’s compaction in the initial and middle stages is crucial for transforming loose subgrade filler particles into a dense state. The subgrade shows nonlinear characteristics of large and small plastic deformation.
