The design of a windmill rotor is critical for harnessing wind energy. In this work, a study is conducted to optimize the design and performance of a rotor blade that is suitable for low wind conditions. The windmills' rotor blades are aerodynamically designed based on the SG6043 airfoil and wind sp ...

Oznake: axial locking;expanding pin system;bolt preload;contact asperities;flanged connection;radial locking;shear resistance;shrink fit;
Bolted connections are widely used in parallel plates and flanged joints to axially lock using the preload generated by the tightening torque and to constrain radial movements of the flanges by the surface friction between mating surfaces. The surface friction depends on the micro-asperities of mati ...
