Through a lot of experiments and analysis, it was pointed out that the twist number of steel wire in torsion test decreased gradually with increasing axial tension load.

The structural features of the system, determination of initial pre-tension, dynamic functions, mechanical behaviors under load and the construction of main nodes, are introduced.

Based on analysing the long-distance tape conveyor and its characteristics of tension, load and mechanic, this paper sets up its optimized speed-driven and acceleration-driven model.
