A THREE-DIMENSIONAL PHOTOELASTIC INVESTIGATION OF A PROPELLER BLADE RETENTION

摘要: In a propeller blade retention, the forces on are transmitted to retention by means of rows balls. A Castolite model typical with two balls was subjected an axial load and transverse bending moment in ratio 100:29. Stress concentration factors, interior stresses, distribution between were determined three-dimensional shear-difference sub-slice method combination stress freezing techniques. Appropriate checks for accuracy results made. addition its value design solution provides excellent demonstration practicality power this new method.
