| 1 | Active Damping of Milling Vibration Using Operational Amplifier Circuit显示文摘The problem of chatter vibration is associated with adverse consequences that often lead to tool impairment and poor surface finished in a workpiece, and thus, controlling or suppressing chatter vibrations is of great significance to improve machining quality. In this paper, a workpiece and an actuator dynamics are considered in modeling and controller design. A proportional-integral controller(PI) is presented to control and actively damp the chatter vibration of a workpiece in the milling process. The controller is chosen on the basis of its highly stable output and a smaller amount of steady-state error. The controller is realized using analog operational amplifier circuit. The work has contributed to planning a novel approach that addresses the problem of chatter vibration in spite of technical hitches in modeling and controller design. The method can also lead to considerable reduction in vibrations and can be beneficial in industries in term of cost reduction and energy saving. The application of this method is verified using active damping device actuator(ADD) in the milling of steel. | Bashir Bala Muhammad Min Wan Yang Liu Heng Yuan | 2018 | Chinese Journal of Mechanical Engineering2018，31，5： | 2 |

| 10 | Synthesis, Characterization and Application of Benzyl-substituted Cyclopentadienyl lanthanide Complexes as Catalyst Precursors for the Syndiotactic Polymerization of Methyl Methacrylate显示文摘Yan-LongBALA, Muhammad D. XIE, Xiao-Min(HUANG, Ji-Ling*Laboratory of Organometallic Chemistry, East China University of Science and Technology, Shanghai 200237, China Benzyl-substituted cyclopentadienyl lanthanide complexes were synthesized and characterized by elemental analysis, MS and IR spectroscopy. The analytical data point out the formation of monomeric, unsolvated complexes. In conjunction with Al(Et)3 as co-catalyst, the title complexes are efficient catalysts for the syndiotactic polymeriza-tion of methyl methacrylate. For the complex (C6H5CH2C5H4)2YCl, under the optimum polymerization conditions (60 ℃, n(MMA)∶n(catalyst)∶n(co-catalyst)=1000∶1∶10), a predominantly syndiotactic (rr=66%) polymer of high molecular weight (Mh=105000) was obtained. | 钱延龙 BALA Muhammad D. 谢小敏 黄吉玲 | 2004 | Chinese Journal of Chemistry2004，22，6： | 0 |
