| Decoration applying with natural stone materials is a fashion at present, as stone materials are the first grade building decoration materials and stone balls are among them. They are widely used in the decoration of modern city squares. The colorful marble balls are spinning under the force of running water and their faces are more beautiful under electric lights.The analysis and research on stone balls have not caused enough attention in the world. In china, few people have made any study on it, in spite of its sophisticated technologies and high profits.This paper analyzes systematically on theory the movement of stone balls, establishing a series of commutating formula of processing parameters and bettering former processing. Patterns which are based on experience and experiment and wasteful in time, nonguarantecable in quality. High production efficiently is then achieved. And the same time, this paper puts forward a relative control system, changes and realizes the adjustment of spinning speed and the fixed increasing the technology and application of stone balls, yielding better economic efficienly.In the end of this paper, there is an appendix of computation program edited by C language, the geometry parameters of stone balls.The research results have high values on both theory and application. |
