Speech Title: Development of Medical and Assistive Devices in Aging Society
Abstract: Recently, aging is accelerating rapidly all over the world. The aging rate, which represents the proportion of the population over 65 years of age against total population, is becoming higher and higher year by year in most of countries. Actually, Japan is the highest aging rate country all over the world. Total population is reducing, while the aging rate keeps rising. Therefore, needs of medical care and nursing care for elderly people are increasing. Thus, development of medical and assistive devices through an application of the Robot Technology (RT) has been promoted. In this talk, some medical and assistive devices developed in my laboratory are introduced.
Prof. Jing Wang, Qingdao University of Technology, China
Dr. Jing Wang got her PHD from Kyushu University of Technology in Japan. She was the visiting scholar to France, Japan, Czech Republic and the United States. She maintained good cooperative relations with Kyushu University of Technology in Japan, University of Auckland in the United States, Tunte University in the Netherlands, INSA in Lyon in France and Leeds University in the United Kingdom. He has been engaged in basic tribology research, and she are the responsible preson of many scientific research projects which are sponsored by National Natural Fund, high-quality courses for Postgraduates in Shandong Province. She published 52 SCI/EI papers. Her students have won awards in many domestic/international academic conferences.
Speech Title: Oil/Grease Film Variation and surface damage in the Process of Reciprocation-Oscillation Transformation
Abstract: In industrial applications, many key components such as gears, chain drives and rolling element bearings, etc., are working under a transient state. Reciprocation, and oscillation are the same form of transient motion with the only difference in the stroke length. Fretting phenomenon is caused by the relative oscillatory movement with small amplitude. On account of being hidden in mechanical movements, fretting becomes one of the major failures of industrial machine systems. In this study, optical interferometry experiments were carried out on a ball-disk test rig to study the change of elastohydrodynamic lubrication (EHL) in reciprocation to boundary lubrication (BL) in oscillation for the contacts of pure rolling and simple sliding motions. Then, using an SRV wear tester, the corresponding tribological performance during the transformation from the reciprocating motion to the oscillating motion under simple sliding condition was evaluated. The experimental results show that the BL area in the contact zone gradually increases with the decrease of the stroke length, so that the area of entrapped oil film by the squeeze effect is gradually decreased. The experiments by the SRV tester revealed that, with the decrease of stroke length, the surface damage become more severe. The article aims to synthesize the variation of the EHL film and the BL film as well as the sliding wear and fretting during the transformation of the reciprocating to oscillating motion. Further, greases are used to explore the film characteristic in reciprocation-oscillation transformation.
