Abstract: The operation simulation of wastewater treatment device based on swirling cavitation degradation has been done by means of CFD software. The condition of swirling cavitation formation and the shape of cavitation distribution were analyzed. The validity of simulation and wastewater treatment device operation were verified according to the testing results of device’s working parameters and degradation for Rhodamine B. The criterion to judge cavitation formation or degradation efficiency has been established. The industrialized enlargement for mini wastewater treatment device has been analyzed by means of simulation. It is useful to establish industrial application foundation of this kind of wastewater treatment device.

Abstract: Dynamic modelling method for disc indexing cam mechanism was presented based on virtual prototype technology according to the analysis of mechanism feature. Rigid-flexible coupled dynamic model was established by means of Adams, Pro/E and Ansys softwares. Dynamic simulation has been done. It follows the analysis of simulation that effects of input speed, and stroke angle to torsional vibration were illustrated corresponding to dynamics simulation. Dynamic characteristics of different transmission functions commonly used in practical engineering were analyzed in detail. The application principle of transmission functions was presented based on dynamic simulation and analysis results. Construction method of transmission function was presented finally.

Abstract: Quick-point grinding technology, suitable to be applied in automobile manufacturing, cemented carbide and ceramic material processing industry, was an advanced ultra-high-speed grinding technology. It is the integration of super-high speed grinding, CBN super-abrasive and CNC flexible manufacturing and so on. The characteristics of quick-point grinding were systematically illustrated. Applications of this technology to process hard-machining materials and shaft parts were also given in this paper. Some problems and solutions corresponding to quick-point grinding technology were presented finally.

Abstract: Construction method of transmission function was presented based on intermittent transmission characteristic of indexing cam mechanism. The transmission function with continuous acceleration has been deduced by an example, and verification method of transmission function was presented based on the virtual prototype technology. A model of parallel indexing cam mechanism was established using the constructed transmission function, and theoretical derivation was verified correctly through simulation.
