Professor Yasuyiki Miyazaki


Prof. Miyazaki is currently with Nihon University, Department of Aerospace Engineering, College of Science and Technology, Japan as a professor. His research areas include: Flexible multi-body dynamics, dynamics of membrane structure; Structural dynamics of gossamer spacecraft (He is a project member of solar sail “IKAROS” launched in May; this year); Folding of membrane; Nano-satellite engineering (His students had developed and launched a 1U CubeSat from India in 2008, and a 20cm class nano satellite from Japan in 2014). He obtained holds a Doctor of Engineering degree form The University of Tokyo, in 1993.

Some of his research experience includes: Nonlinear finite element analysis of 3D large deformation of thin rod; Elastic impact ; Interaction of structure and rarefied gas flow;

Topological optimization; Development, launch and operation of nano-satellite (launched in 2008); Dynamic analysis of flexible space structures (University of Colorado, Boulder, CO, U.S.A.); Localized Lagrange multiplier method of elastic impact problem (The University of Tokyo, Tokyo, Japan.); Analytical solution of three dimensional elastic; Geometrically nonlinear analysis of thin plate (Miura-ori, and so on); Structural concept of Tension Truss Antenna. Prof. Miyazaki has worked with a number of universities around the world as visiting professor.

Yasuyuki Miyazaki received his PhD degrees in Aeronautics from the University of Tokyo, Japan in 1993. He has been a faculty member of Nihon University, Japan since 1993. He was a visiting professor of University of Colorado from 2001 to 2002, and was a visiting professor of JAXA from 2006 to 2008. He is a professor of Nihon University since 2008.

His major research area is flexible multi-body dynamics and structural dynamics of gossamer spacecraft. He has joined the design and development of Japanese solar sail IKAROS which was successfully launched in 2010 by JAXA. He is also a member of SIMPLE project which is a space demonstration of inflatable structures on the exposed facility of Japanese experimental module JEM in International Space Station. SIMPLE was launched last in 2012 and the on-orbit experiment was successfully achieved.

He has been leading a student pico-satellite project in Nihon University since 2000. His students developed two Cubesats, one of which was launched from Russia in 2006 and the other was from India in 2008. His students are now developing the next pico-satellite of 20cm cube which will demonstrate the inflatable membrane structure in space. The pico-satellite named SPROUT was lawill be launched in 2013 by H-IIA rocket from Japan.

He is a member of Japanese 50kg class nano-satellite project, named“HODOYOSHI”, which is led by Prof. Nakasuka of University of Tokyo. Many researchers and engineers all over Japan join the HODOYOSHI project and four nano-satellites has been launched. He works for the research and development of deployable structure in the project.
