25. Based on SolidWorks COSMOS 2.5 Tons, 4m•s-1 High Speed the Elevator Drive's Finite Element Analysis

Author

Lu, Feng, Bao, Yuan, Zhou, Xiang Guo, and Wang, Ya Jun

Abstract

Drive as the high-speed elevator's power input device, its function is to drag car and counterweight running in the hatchway. Drive's working status has significant impact to elevator's safety, dependability and comfort. Through the FEA on high-speed elevator's drive machine, and basis theoretical is used to provide reason for stress calculating and theoretical analyses. First, treat the drive device's stress with reasonable structure simplifying. Second, by the Plug-in SolidWorks COSMOS exert 3D modeling on load and constrain. The last, executing the FEA gets stress and strain cloud. Contrast the FEA analysis on the drive device with actual observation outcome, it shows that they are similarity, the analysis outcomes demonstrate the method of research to be reasonable, it has great meaning for high-speed and great capacity elevator's research. Provide directions for in-depth development.

26. Study on Electrical Sliding Wear Property of Cu/MoS2/Mo Composites

Author

Ma, Dou Qin, Xie, Jing Pei, Li, Ji Wen, Wang, Ai Qin, Wang, Wen Yan, Zhang, Zhi Chao, and Wang, Ya Jun

Abstract

In this paper, the Cu/MoS2/Mo composites were prepared by the powder metallurgy technology. The friction wear test was tested by the HST-100 High Speed Electric-tribometer. The microstructure and wearing surface morphology were examined by SEM and EDS. The electrical sliding wear behavior of the composites was discussed. The results indicated that the dense composites are obtained; the wear mechanisms of Cu/MoS2/Mo are mainly abrasive wear and adhesive wear with arc erosion; the effects of current intensity and sliding velocity on the wear property of the composites are complicated, and the composites show the best property when the current intensity is 60A and the sliding velocity is 40m/s.
