Research about Slider Three-Dimensional Frictional Contact Problem of the Polygonal and Similar-Oval Jib

Abstract:

The existence of boundary condition and friction are difficult to predict which makes the sliders contact situation extremely complex. The actual response of the contact region becomes a tough research by using traditional method. Taking the cylinder supporting function into account, the polygonal and similar-oval Jib models are established. Research of the stress distribution and the stress concentration phenomenon is analyzed. The results indicate that stress distribution of the sliders of the similar-oval Jib is more uniform in comparison with the polygonal Jib that it can ameliorate the stress state of the contact region and enhance the partial stability of the Jib.
