Solid models of low speed stage gear mesh in mobile tower crane transmission system were established by using Pro/E2001 and and then imported into ANSYS. The mesh contact model was then established by using three different elements,SOLID45,TARGE17 and CONTA174,to dividing the mesh.
In the experiment, the density and compressive strength increase from (1.28g/cm~3) to 1.77g/cm~3 and from 10.1MPa to 55.0MPa respectively when the average particle size of the granular pitch coke as reinforcement rises from 44.2 to 206.3mesh.
The result indicates that the filtering strength is increased by a factor of two in case of phosphoric acid slurry concentration reducing from 0.03-0.05 g/mL to 0.02-0.03 g/mL, liquid/solid ratio reducing to 2.0:1-2.5:1, ore powder granularity increasing to 87.5% passing 100 mesh.
Anewwavelet-based geometric mesh compression algorithm was developed recently in the area of computer graphics by Khodakovsky, Schr?der, and Sweldens in their interesting article .
This leads to a very efficient geometric mesh compression algorithm as proposed in .
As a result, the algorithm in  outperforms several available geometric mesh compression schemes used in the area of computer graphics.
We confirm here that the shifts and dilations of the wavelets used in  for the regular mesh, as expected, do indeed form a Riesz basis of L2(?2) by applying the more general theory established in this article.
Our main result is that the rate of convergence of the two proposed iterative schemes depends only on the mesh norm and the
