| 1 | Harmonic Current′s Coupling Effect on the Main Motion of Temper Mill Set显示文摘The paper probes into a probable condition that causes temper mill chatter from aspect of electromechanical coupling of complex electromechanical system, and mainly studies the effect of temper mill electrical driving system harmonic current on the main motion of temper mill set. Aiming at the electrical driving system of CM04 temper mill, the effect of harmonic current is analyzed and evaluated according to different load. Combining the features of CM04 temper mill′s structure and its working state, the paper discusses in every detail how the harmonic current in main circuit, which can be regarded as a disturbance via feedback control circuit , influences main motion of temper mill set. | HE Jian-jun YU Shou-yi ZHONG Jue | 2000 | Journal of Central South University2000，12，3： | 6 |
| 2 | DESCRIPTION AND PREDICTION OF CATASTROPHE OF VIBRATION STATE FOR FAULTY ROTORS显示文摘A sudden increase of vibration amplitude with no foreboding often results in an abrupt breakdown of a mechanical system.The catastrophe of vibration state of a faulty rotor is a typical nonlinear phenomenon,and very difficult to be described and predicted with linear vibration theory.On the basis of nonlinear vibration and catastrophe theory,fhe eatastrophe of the vibration amplitude of the faulty rotor is described;a way to predict its emergence is developed. | Chen Anhua Zhong Jue | 1996 | Transactions of Nonferrous Metals Society of China1996，6，1： | 5 |
| 3 | OPTIMAL CONTROL OF AN ACTIVE SUSPENSION SYSTEMEMPLOYING HIGH SPEED ON/OFF SOLENOID VALVE显示文摘Previous studies have confirmed that an active suspension system with high speed ON/OFF solenoid valves could provide the same vibration isolation efficiency as that of system with pressure proportional valve. In this study, by using Linear-quadratic optimization technique and Kalman filter method, an optimal regulator controller with a state observer was designed for the proposed system. Simulation and experimental research was conducted on a quarter car model. The simulation analysis of the system frequency characteristic suggested that the peak value of magnitude response curve in the case of system with an optimal controller would be lowered significantly, and the experiment results also showed that an improvement in the vibration isolation effect was obtained in using the designed optimal controller over the sky hook damper controller. | Liu Shaojun Zhong Jue Li Qingchun (College of Mechanical and Electrical Engineering,Central South University of Technology, Changsha 410083, China)HironaoYAMADA YoshikazuSUEMATSU(NAGOYAUniversity Japan) | 1997 | Journal of Central South University1997，9，2： | 4 |
| 4 | MICROSTRUCTURE CHARACTERISTICS AT THE BOND INTERFACE显示文摘Lift-off and section characteristics at the interface of thermosonic bond are observed by using scanning electron microscope (KYKY2800) with EDS-test. Results show that the peeling underdeveloped bonds simulate a torus (or doughnut) with an unbonded central region and ridged peripheral region is bonded hardly. Inside roundness at flip chip bonding center are discovered. Bond strength is located between the severely ridged periphery and the non-adhering central area of the bond. For constant force and time, the ridged area of the bond pattern increases when more power is applied. For constant force and power, the ridged location of the bonded region moves closer to the bond center with time. Results of EDS-tests at Au-Al and Au-Ag interfaces show that Kirkendall diffusibility at Au-Ag interface occur and the diffusing speed of Au-atomic is faster than that of Ag,and that intermetallic compounds at Au-A1 interface is generated possibly. And these would be helpful for further research about thermosonic bonding. | Li Junhui Han Lei Zhong Jue | 2005 | Chinese Journal of Mechanical Engineering2005，18，4： | 2 |
| 5 | SUB-NANOMETER POLISHING OF MAGNETIC RIGID DISK HEADS TO AVOID POLE TIP RECESSION显示文摘For the purpose of solving the problem that too large pole tip recession (PTR) is produced in magnetic rigid disk beads by mechanical polishing,a chemical mechanical nano-grinding experiment is performed by using a float-piece polisher with a tin plate to achieve a more plane and smoother surface. A basal solution, addition agents and a range of pH value are suitably selected to find a kind of slurry, with which the PTR can be controlled on sub-nanometer scale and the giant magnetic resistance (GMR) corrosion and electrostatic damage (ESD) can be avoided. Moreover, the cause that TiC protrudes from the substrate surface of the heads is studied. The appropriate shape and size of diamond abrasive are selected according to the chemical activation of Al_2O_3 and TiC in the same slurry. In this way, the chemical and mechanical interactions are optimized and the optimal surface that has small PTR and TiC asperity is achieved. Ultimatily, the chemical mechanical nano-grinding in combination with mechanical nano-grinding is adopted. Sub-nanometer PTR is achieved and the TiC asperity is eliminated by the chemical mechanical nano-grinding with large size of monocrystalline followed by mechanical nano-grinding with smalle polycrystalline diamonds. | SHEN Rulin ZHOU Li ZHONG Jue | 2008 | Chinese Journal of Mechanical Engineering2008，21，4： | 2 |
| 6 | Therapeutic Observation of Warm Needling plus Tuina for Senile Functional Constipation显示文摘Objective: To observe the clinical efficacy of warm needling plus tuina in treating senile functional constipation. Methods: Ninety elderly patients with functional constipation were randomized into two groups. Forty-six patients in the treatment group were intervened by warm needling plus tuina; the other forty-four patients in the control group were intervened by San Huang tablet. Results: In the treatment group, 19 patients were cured, 24 cases showed improvement, 3 cases failed, and the total effective rate was 93.5%; in the control group, 16 patients were cured, 18 cases showed improvement, 10 cases failed, and the total effective rate was 77.3%. There was a significant difference in comparing the therapeutic efficacy(P<0.05), and the therapeutic efficacy of the treatment group was higher than that of the control group. Conclusion: Warm needling plus tuina can produce a higher therapeutic efficacy than taking San Huang tablet in treating senile functional constipation. | Li Ying Hua Yu Zhong Ning Hong Jue | 2014 | Journal of Acupuncture and Tuina Science2014，12，5： | 2 |
| 7 | Ginger-indirect moxibustion plus acupuncture versus acupuncture alone for chronic fatigue syndrome:a randomized controlled trial显示文摘OBJECTIVE:To assess the efficacy and safety of gingerindirect moxibustion for chronic fatigue syndrome(CFS).METHODS:In this central randomized,controlled trial,290 CFS participants were recruited and randomly allocated to group A(ginger-indirect moxibustion plus acupuncture)or group B(acupuncture alone).The study consisted of a treatment period of 8 weeks with a total of 24 treatments(3 sessions per week,every other day),and a follow-up period of 12 weeks.The outcome was measured by Fatigue Severity Scale(FSS),Psychological Health Report(SPHERE),the Self-rating depression scale(SDS)and the Hamilton anxiety scale(HAMA)at baseline,2,4,6,8,12 and 20 weeks.RESULTS:With the treatment undergoing,the changes of FSS,SPHERE,SDS and HAMA scores in both groups increased gradually,and the effect maintained at the 12th week.Between groups,significantly higher score changes were seen in group A in FSS after 4 weeks treatment(11.94 vs 9.12,95%CI:0.94,4.7)and in SPHERE after 2 weeks treatment(3.7 vs 2.27,95%CI:0.56,2.31).But for SDS and HAMA,the improvement did not differ significantly between groups.No severe adverse events were reported.CONCLUSION:Ginger-indirect moxibustion is a safe and effective intervention to relieve fatigue and accompanying physical symptoms of CFS. | MA Tingting WU Jie YANG Lijie FENG Fen YANG Huilin ZHANG Jinhua ZHONG Yanjin NING Qing HUANG Lirong LIN Youbing YAN Jue CHEN Guiquan HOU Tianshu WANG Li REN Yuanfang TAN Jing | 2022 | Journal of Traditional Chinese Medicine2022，42，2： | 2 |
