The application of domestic insoluble sulfur OT-20 in the belt compound and transition layer compound in TBR tire was investigated.

Generating Blending Surface Based on Physical Energy Minimization;

The Research of N-sided Surface and the Generation of Blending Surface Basing on Finite Element Mesh;

This paper presented two methods for NURBS surface extension, and combining with the characteristics of MPF, the blank holder blending surface system of Multi-Point Forming was designed.

Generating blending surfaces based on dynamic PDE

Its implicit form and parametric form are given to prove G 3-continuity between the blending surface and given surfaces.

At the same time,the theory and methods of blending surfaces generation is one of attractive fields.

Aiming at unidentity between theoretical research and practical processing, this paper, also at the first time, proposes the concept of cutting transition surface of the wormgear by hob, and correspondingly, establishes the conditions under which the solution of the turning point problem can be worked out.

Vector equations of the tooth bearing and transition curved surface at dedendum are derived for Gleason spiral bevel gears by SGM and solved by Newton s iterative method with relevant computer program provided so as to implement the curve emulation of tooth shape.
