素線動力学を用いたCIC導体中の摩擦発熱の解析

Strand motion in a cable-in-conduit conductor (CICC) has been simulated dynamically by means of solving the equation of motion of each strand in order to clarify the phenomena in CICC during energizing, which is necessary to evaluate stability. Using the wire dynamics simulation, each strand position and detailed frictional heating in the conduit could be calculated dynamically. It was clarified that rearrangement of the strands takes place during energizing and this is accompanied by intermittent frictional heating. The frictional heating between wire and conduit was found to be larger than that between wires. The effects of frictional heating on stability of the CICC could be quantified.
