Analysis on bending and twisting mechanical characteristics of CICC based on Quasi-Isotropic Strand
HTS CICC has broad application prospects in high magnetic fields and large magnets(such as accelerators and future fusion energy devices).In order to withstand large Lorentz forces and operate at low temperatures,HTS CICC needs to have high mechanical and thermal stability.The mechanical properties of CICC based on Quasi-Isotropic strand were analyzed,including the relationship between bending radius,torsional pitch and critical current.The stress distribution,critical bending ra-dius and critical torque of CICC under bending and torsional loads and their combined loads were obtained by the method of simu-lation calculation.The obtained critical bending radius and critical torque are of great significance for the application of large magnets under high magnetic field and low temperature current leads.
