| Outline of Final Research Achievements |
In this research, we aimed to propose the method to simultaneously realize wire lateral vibration suppression, tip position control, and suppression of tension loss only by controlling the length of the wire. Through the numerical calculations, we confirmed that there is a correlation between the wire lateral vibration amplitude and the axial length change; hence, the possibility of the positioning control in the two-dimensional plane by the axial feed as the concept was obtained. From the above-mentioned results, this control method can be applied not only to the control of the elevator rope and the crane wire on the ground, but also the lightweight and flexible wire is suitable for use in the space structure. And we also could expect to be active in scientific observation and resource discovery.
