Simulation on Hitting Probability of MMW Remote ControllingTrajectory Correction Munition Intercepting

Hu Ronglin,Li Xingguo

Strategic Study of CAE 2007, Volume 9, Issue 10,   Pages 65-70

Abstract:

The basic principle of millimeter wave remote controlling munitions (MMW-RCTCM) is demonstrated in the introduction.  Then the concept of correctable intercepting flow is proposed.  And the anti-air shooting model of millimeter wave remote controlling munitions (MMW-RCTCM) intercepting mobile anti-ship missile (MACM) is established in section 2 and 3.  Subsequently,  the hitting probability of single MMW-RCTCM vs.  single MACM as well as MMW-RCTCM flow vs.  single MACM and MMW-RCTCM flow vs.  MACM flow are analyzedin detail.  The probabilities of the above are simulated based on the parameters of the two sides of attacking and intercepting in the 5th section.  It is illustrated that comparing with the non-controlling munitions,  the efficiency of MMW-RCTCM is increased remarkably.  At the last,  it is concluded that the MMW-RCTCM can resist the attacking of saturate flow; ultra-sonic MACM.

A reliable and practical reference objective for the deviation diagnosis of energy system parameters

Liping LI, Zheng LI,

Frontiers in Energy 2009, Volume 3, Issue 4,   Pages 440-445 doi: 10.1007/s11708-009-0051-8

Abstract: The core objective to optimize a complex energy system is to set the reference target to guide the parameter adjustment of system operation. In this paper, a new case-based approach is proposed based on an online performance assessment program and its long-term operation data for a large power unit. The online model of a coal-fired power unit’s performance assessment is demonstrated, and the distribution pattern of the performance index is revealed by statistical analysis of the abundant data. The fundamental issues (representation of the similarity of two thermal processes, similarity measure, etc.) are tackled. The key sections and key parameters for the completion of similarity determination are proposed, which are essential to realize a case-based strategy. A full-scope simulator of power unit is used to test the availability of the method. The advantage of the case-based approach is the integrality of information over other methods.

Error measurement and assemble error correction of a 3D-step-gauge

MAO Xinyong, LI Bin, SHI Hanmin, LIU Hongqi, LI Xi, LI Peigen

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 4,   Pages 388-393 doi: 10.1007/s11465-007-0067-x

Abstract: A new artifact called 3D-step-gauge consisting of a pyramid array and a compound, is proposed to calculate geometrical errors for machine tools. Only one point on each profile of the pyramid in the array is probed, and its center coordinate can be calculated. Then, the intervals of the pyramids can be transfered a length standard to measure errors. Considering the differences in the structural parameters and the location of the pyramids, a volumetric error measurement method of discrete points is presented. Furthermore, the location errors between the calibration state and the measurement state are studied and their influences on the accuracy of the position measurement are investigated on an actual machine tool. The 3D-step-gauge was tested on an actual machine tool and the measurement result shows quick assembly, convenient measurement, and high accuracy.
