Abstract:

Based on the standard curve of the catenary,the calculation formulas of non load sketch and tension of suspension rope are deduced.By establishing state coordinate equation,the relationship between load horizon tension and load deflection is deduced,load sketch and tension of suspension rope is solved by Newton iteration numerical method.

Key words: Suspension rope, Catenary theory, Newton iteration method, Sketch, Tension
