Welcome to the Granular Dynamics Lab at Shibaura Institute of Technology !

Handling Solutions for Granular Materials

-Development and Numerical Analysis-

Please also visit our Japanese website!!

　There are many different types of handling equipment for granular materials such as sand, salt and so forth. This laboratory investigates the dynamics of granular materials and develops novel granular handling equipment that use the electrostatic forces or the vibration. Moreover, various apparatuses are designed and made to reproduce vibration problems in engineering, such as natural frequencies, mode shapes and frictional vibration. These apparatuses are effective in a classroom lecture of vibration engineering.

We are extremely interested in:

・particle dampers,

・removal of foreign objects in dried foods,

・granular simulation,

・separation of conductors and nonconductors,

・separation of plastic mixtures,

・motion analysis of a foreign object between relay electrodes,

・DEM－FEM coupling approach for dynamical analysis of granular systems.
