Compare and Analyse of Unit Deforming Force and Boundary Conditions in Model Element of Cylinder Upsetting;

Analysis for Temperature field of upset cylinder in quenching process by FEM;

Study on Evaluation of Cylinder Geometric Parameters in Reverse Engineering;

90×10~4,the flow separation around the circular cylinder can be suppressed effectively,the separated flow field can also be improved greatly owing to the flow disturbance.

The expression of K1 for small values of the ratio of the radius of the crack to the length of the circular cylinder is obtained by seeking an iterative solution of this equation.

In this paper, by the use of the 3D equations of linear elasticity, the free vibration problem of a transversely isotropic finite length circular cylinder is solved.

The nonlocal friction law proposed by oden et al is adopted in order to consider the nonlocal friction effect of the asperities on the stress distribution about superplastic wire extrusion of cylindrical body through a cone-shaped die.

Research of non-resin winding cylinder preforming retracing cosine curve;

On the base of the research of the non-resin winding cylinder preforming technique,particular arithmetic used to develop the computer software was indicated.

In this dissertation, the technology of cylinder non-resin winding preforming was put forward and studied comprehensively and systematically.

Study on influencing factors for sound radiation characteristics of finite length cylindrical shells;

Taking an actual project for example,the calculation of internal forces of a large diameter silo under different working conditions according to cylindrical shell theory is described in detail.

Some geometric sizes of a metal cylindrical shell structure as variables are optimized to minimize the explosive that broke the inner structure in an exploding process subjected to the maximal stress in the outer structure.
