Device Design And Experimental Study Of Loquid-Particle Two-Phase Compulsive Circumfluence Oriented Hole Surface Finishing

The research is supported by the nation science fund project (50675149) which research on "Theory and Technological Basis of Liquid-Particle Two-Phase Compulsive Circumfluence Oriented Hole Surface Finishing", to research liquid-particle two-phase compulsive circumfluence finishing technique. Through the circulation occurs device, compulsive circulation is formed by the liquid, which has a certain pressure. It stimulates particles to make circulation movement. Particles have the function of rolling, scoring, etc., for the hole surface by means of strong centrifugal force, and the liquid has the tremendous energy to impact the hole surface, to achieve the hole surface finishing.The primary content of thesis:expatiating traditional technology of hole surface finishing; introducing correlation knowledge of two-phase flow and spiral flow and the finishing principle of liquid-particle two phase compulsive circulation finishing, carrying through simulation of some equipment former be mentioned by FLUENT software, deciding to adopt set of liquid-particle two-phase compulsive circulation flows finishing considering simulation result. difficult or easy in manufacturing and cost etc; carrying through correlation device design by selected equipment; finally, the device be processed to put up some basic experiment, so that the feasibility of this technology and infection of quality and efficiency in magnitude of liquid flux,nozzle amount,nozzle position and so on can be validated.The success application of this technology will have a broad scope of application, and create a new approach to solve the hole surface finishing problems. It can improve overall physical and mechanical properties of part surface, providing a favorable theoretical basis and data for the wider application of this technology. Simultaneously, the traditional finishing technologies and non-traditional finishing techniques can be further improved, enhancing finishing skill levels, promoting the development of related industries, having significant social and economic benefits.
