Multi-layer spiral compact cable based on high-temperature superconducting tapes is a potential candidate for large-scale superconducting applications. During magnet processing and operation, superconducting tapes and cables are subject to complex mechanical and electromagnetic forces. Plentiful studies are conducted on the cable's mechanical performance during the preparation process and the operating electromagnetic characteristics separately, but still lack sufficient focus on the electromagnetic-mechanical coupling. In this paper, an electromagnetic-mechanical field co-simulation is carried out. The effect of residual strain from the winding process is included. The electromagnetic force characteristics in spiral cables as well as mechanical response are studied. This study is fundamental for further analysis on large-scale magnets made of spiral cables that are subject to large Lorentz forces in operation with preparation-induced residual strain.
