149 磁力支持天秤装置による流体振動制御

抄録

A MSBS supports the model by both a permanent magnet and an electromagnet. Then, a permanent magnet can fill it up in the model as well. This MSBS doesn't have support interference effects because the model is supported by magnetic force and it can measure fluid mechanical power and moment acting on the model, so we can experiment in a wind tunnel ideally. The objective of this research is to: 1) set up a MSBS 2) evaluate a) fluid characteristics of self-excited vibration of the model due to the turbulence; b) vortex induced vibration; c) fluid characteristics of liquid by open loop transfer function; and 3) control this fluid vibration. Using this test, fluid force acting upon the sphere in water is evaluated.
