The conference selected eight best paper awards and recommended a large number of excellent conference papers to the IJMSD and other journals. The proceedings of the conference will be published by the Institution of Engineering and Technology (IET) and indexed by Ei Compendex.

On the morning of the 25th, the first ICMSD opened at the Shangri-La Hotel, Nanjing, with Prof. Weihong Zhang, a member of the Chinese Academy of Sciences and a member of the ICMSD Standing Steering Committee, presiding over the opening ceremony. Prof. Mengyin Fu, the Chairman of the Local Organizing Committee of the first ICMSD and the President of Nanjing University of Science and Technology, delivered a welcome speech. Prof. Xiaoting Rui, a member of the Chinese Academy of Sciences and the ICMSD Chairman, delivered the opening speech. “Various mechanical systems, such as vehicles, airplanes, ships, high-speed trains, satellites, launch vehicles, space stations, robots, and machine tools, concern the economy and people's livelihood, and symbolize the comprehensive strength of a nation's science and technology. Their development is one of the main lines of the progress of human civilization and science, technology, and industry, which depended largely on the science and technology of mechanical system dynamics. By accurate dynamics modeling, fast computation, optimal design, simulation, and test, the mechanical system dynamics studies the objects’ motion laws and interaction of various mechanical systems during their whole lifecycle, including the design, manufacturing, testing, evaluation, and utilization, and involves multi-physics field such as force, electricity, light, magnetism, heat, sound, flow, and gas. Due to its important role, it has become one of the cornerstones of modern science, technology and industry such as machinery, aeronautics, astronautics, ship, and transportation, thus has been widely valued by countries around the world,” was pointed out by Prof. Xiaoting Rui (see Figures 4-6).

Profs. Daining Fang, Aki Mikkola, Marco Amabili, Pierangelo Masarati, and Xuping Zhang, as members of the ICMSD Standing Steering Committee, gave speeches (see Figures 7-11).
