Based on the engineering background of Tangkou in Shandong province, this thesis carries out mining-induced stress distribution law comparative study and analysis of 2313 working face which is lying below-1100 miles, using methods of theoretical analysis, numerical simulation and field measurement, and obtains the limited synergistic effect of mining-induced stress variation and working face advancing steps under the condition of kilometer-deep shaft. That is, with the increase of working face advancing steps, there will be a corresponding increase in the advanced abutment pressure peak, sphere of influence, and the distance from the peak position to the coal wall, within its limit value. The conclusion of this study have some guidance for the safe production and support design of working face in kilometer-deep shaft.

The contact analysis model of high speed centrifugal atomizer is created and stress distribution law is obtained by using ANSYS FEM software in this paper. The stress distribution along the axial direction is uneven, the stress of the small end of the taper is large and the stress concentration appears on both ends of the taper. In addition, the factors which influence the interference fit stress are researched and discussed. The interference fit stress is mainly influenced by the shrink range, while the influence from the friction coefficient is very weak. Comparing with the conventional design, the position and value of the stress and deformation of the parts can be known exactly and thoroughly by using the approach proposed in this paper. The method provides a very valuable reference to designing the best shrink range for engineering application.

s The longitudinal impact between rigid body and variable cross-section elastic rod with fixed boundary condition was studied, the velocity and stress distribution law during 1st impact wave period was derived for the variable cross-section rod, the influence of cross-section change rate on rod response was discussed. Some examples calculations were carried on, It is shown that the cross-section change rate is a significant influencing factor for the velocity and stress distribution in the rod during impact.
