  • Intensity Analysis of Pretightening Bolt of Turntable Bearing

    applied to the turntable bearing of wind power is one of the examples. Because more case studies can determine the range of the load, simulation and analysis of the load can be performed within bearing life. However, in order to calculate the work load of the turntable bearings and bolted connection, we generally define the axial force Fax,
