In order to master the mechanical characteristics of single helical structure (e.g., rope, cable, spring, etc.) and design helical structure such as the non-rotate rope used in aviation field for rescuing personnel and mine hoisting or exploitation, explicit expressions of axial strain, helix angle and laying radius for helical structure were obtained. According to two operating conditions that the bottom end swivel of helical structure was restricted and free, axial displacement and twist angle expressions of helical structure with concentrated mass and extra load in hanging status were deduce. By using these formulations, the design method for axial elastic displacement of terminal limited to a reasonable value and the non-rotate helical structure were discussed as an analysis example.
