MR流体を用いた持ち上げ操作の受動制御

抄録

The inherently safe design, which is prioritized by the international safety standard ISO12100, requires assurance that a machine will not inherently output more than humans can withstand. MR fluid is a functional fluid that can control the phase change from liquid to solid by magnetic field, and is highly responsive. At present, there are many studies using MR fluid, and the number of research reports is increasing. However, no control system that actively utilizes the characteristics of MR fluids has been implemented. Here, a control system that actively utilizes the characteristics of MR fluid and transmits the available energy by the MR fluid when necessary is newly developed and its control performance is verified. Since large amounts of energy are not transmitted by slipping of the MR fluid, it is possible to suppress output to within safe limits for humans.
