Under the agreement of science intercommunication concluded in 1993 between Beijing Institute of Technology and Tokyo Institute of Technology, many kinds of intercommunion had been held up to present. The intention of this workshop is to bring together scientific and engineering researchers to discuss new developments in the field of mechanical engineering, and meanwhile to promote the international cooperation between Beijing Institute of Technology and Tokyo Institute of Technology. The biennial event has been successfully held in Beijing and Tokyo in 2003 and 2005. Now, we prepare the 3rd Joint Workshop of Mechanical Engineering for researchers of both universities. Every researcher in the field of mechanical engineering is welcome to join this workshop. To further enhance exchanges and cooperation between Beijing Institute of Technology and associate organization in Japan, we also invite researchers with the exception of the two universities to take part in this event.
