Research on the Simulation of Friction Material Surface Topography Run Bo Ma 1,a, Shi Meng Xu 1 and Jian Hua Du 2 1Section of Mathematics, Academy of Armored Force Engineering, Beijing 100072, P.R.China 2Department of Equipment maintenance and Remanufacturing, Academy of Armored Force Engineering, Beijing 100072,P.R.China a13810470589@139.com Key words: composite materials; fractal interpolation; asperity; non-parametric hypothesis test Abstract.
Through analysis and research on the surface topography of reinforced copper matrix composite materials, taking advantage of fractal statistical method to discuss distribution law about characteristics parameter which symbolizes the asperity, combining Monte-Carlo method with fractal theory to set up mathematics model of characteristics parameter which symbolizes size of asperity , talking about the construction of iterated function system in fractal interpolated theory, a easy realizable friction materials surface topography simulation algorithm was put forward.
Let friction material plane is a square with bound length L, noting and as maximum diameter and minimum diameter respectively, and is number of asperity.
In conclusion, friction material surface topography simulation map was given in figure 1.

The reverse kinetic problem is solved in the temperatures range of the chemical–technological process for roasting phosphate raw materials on conveyor indurating machines.
The achievement of high efficiency of thermal preparation depends on the conditions of the raw materials heating in roasting devices [4].
The second: the values of the pre-exponent and the type of the function f(n) are determined for materials with homogeneous in shape and form reacting inclusions or their effective values, when it is impossible to set structural parameters.
