	Motion mechanism analysis of a two-degree-of-freedom spherical motor (EI CONFERENCE) 会议论文 OAI收割 2nd International Conference on Information Engineering and Computer Science, ICIECS 2010, December 25, 2010 - December 26, 2010, Wuhan, China 作者: Guo K. 收藏 \| 浏览/下载：20/0 \| 提交时间：2013/03/25 The working principle of a two-degree-of-freedom piezoelectric spherical motor using only one piezoelectric element was analyzed. The resonance frequencies of the motor's plate type piezoelectric vibrator were calculated by finite element method. The computer simulation was executed to analyze the motion trajectory of the four contact points between the stator and the sphere. Simulation results verified that the four contact points can form timing reasonable elliptical trajectories which re designed to drive the sphere to form two rotation degrees of freedom. The conclusion indicated the formation of two-dimensional movement mechanism of the spherical motor. 2010 IEEE.
	Research and development on the valve-less piezoelectric pump with unsymmetrical corrugation chamber bottom (EI CONFERENCE) 会议论文 OAI收割 2006 IEEE International Conference on Information Acquisition, ICIA 2006, August 20, 2006 - August 23, 2006, Weihai, Shandong, China 作者: Zhang J.; Li D.; Zhang J.; Zhang J. 收藏 \| 浏览/下载：18/0 \| 提交时间：2013/03/25 The valve-less piezoelectric pump is more suitable for minimization and microminiaturization than the valve piezoelectric pump especially for the Microelectromechanical System (MEMS) because of its simple structure. However in order to control the flow direction of the fluid through the pump some assembles have to be attached outside the chamber. And it is no doubt that these assembles will take some space and hinder its further microminiaturization. In this paper a novel valve-less piezoelectric pump with unsymmetrical corrugation chamber bottom (UCCB) is presented. It ingeniously takes advantage of the space of the chamber by developing its bottom into a unsymmetrical corrugation shape along the axis of the inlet and outlet. As a result a series of diffuse pipes and nozzle pipes (or wedge-shaped pipes) which substitute the regular diffuse/nozzle elements fitted outside the chamber are alternatively formed between the unsymmetrical corrugation chamber bottom (UCCB) and the piezoelectric vibrator. The piezoelectric vibrator is opposite to the UCCB. And these diffuse pipes and nozzle pipes are able to force the fluid in the chamber to flow along a single direction when the pump works. And then the mathematic model is established to present the relationship between the mean energy loss and the flow rate of the pump. Basing on the mathematic model the theory on the pump working is analysed. Finally a real UCCB valve-less piezoelectric pump is manufactured and the test with it is carried out to verify the theory above-mentioned. 2006 IEEE.
	Research on the close noise field of the piezoelectric pump (EI CONFERENCE) 会议论文 OAI收割 2006 IEEE International Conference on Mechatronics and Automation, ICMA 2006, June 25, 2006 - June 28, 2006, Luoyang, China Jizhuang L.; Jianhui Z.; Shouyin W.; Qixiao X.; Desheng L. 收藏 \| 浏览/下载：53/0 \| 提交时间：2013/03/25 Restraining the noise meanwhile improving the dynamic characteristics of the driving power of piezoelectric pump effectively are the final purposes of doing research on the reciprocating and flexural vibration of the piezoelectric vibrator. However among many papers regarding piezoelectric pump there are very few papers about the research on the noise of piezoelectric pump. This is far less than the research on the application of the piezoelectric pump in other fields. In this paper the research on the flexural vibration deformation and vibration radiation noise of the piezoelectric vibrator are carried out. Firstly the vibration equations of the piezoelectric vibrator are built and flexural vibration deformation function is deduced. Then the simplified vibration model of the piezoelectric vibrator is introduced by using vibration theories of micro-area piston. Furthermore theoretical calculation equations of sound pressure in close noise field and noise contribution equation of fluid in pump are deduced. Finally a comparison is made between the theoretical calculation value and experimental value and the contribution quantities of the piezoelectric vibrator and fluid in pump are obtained respectively under different frequencies. The consequence approves that the theory introduced by this research is true. 2006 IEEE.
