The experimental and numerical transmission spectra consistently display a striking transmission peak at wavelength much larger than any characteristic length of the microstructure (e.g.  about 20-fold of the lattice constant)  which can not be directly interpreted by the existing mechanisms. Both the LC-circuit-based microscopic picture and the effective-medium-based macroscopic model are established to capture the essential physics behind such unexpected resonance at the deep subwavelength scale. 2012 IEEE.   Finite element model and analysis for micro-cutting of aluminum alloy 7050-T7451 (EI CONFERENCE) 会议论文  OAI收割 2012 International Conference on Machine Design and Manufacturing Engineering, ICMDME 2012, May 11, 2012 - May 12, 2012, Jeju Island, Korea, Republic of 作者:  Zhou J.;  Wang F.;  Wang F. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 In this paper  a finite element model with respect to actual state of micro-cutting is established by adopting software of ABAQUS/Explicit. Based on the FE model  the cutting force and specific cutting force with various uncut depth of cut with different cutting edge radius are compared and then analyzed with regard to this simulation. In micro-cutting  the nonlinear scaling phenomenon is more evident with the decreasing of uncut chip thickness. The likely explanations for the size effect in small uncut chip thickness are discussed in this paper.

The use of optimal tracking controller  simulation experiment of the control system based on optimal tracking controller is carried out. The simulation result  instead of traditional PID controller  the control system based on optimal tracking controller is designed  in comparison with the system based on a PID controller  can effectively improve the scanning accuracy of space scanning mirror control system. State space model of the control system is established  shows that the scanning mirror control system using optimal tracking controller instead of PID controller has higher scanning accuracy and faster response.
