Help on Torsional stiffness of a non-rotational wire rope

Help on Torsional stiffness of a non-rotational wire rope

Help on Torsional stiffness of a non-rotational wire rope

(OP)
I am trying to find out how to calculate the torsional stiffness of a wire rope. Ultimately I am wanting to determine the torque required to rotate the wire rope.

RE: Help on Torsional stiffness of a non-rotational wire rope

I'd be a bit amazed if a wire rope manufacturer couldn't tell you, or a crane or winch manufacturer.

From first principles it is a rather tricky problem.

So, are you trying to analyse it or just get an answer?

RE: Help on Torsional stiffness of a non-rotational wire rope

I am with Greg there. The best source is going to be the manufacturer. Besides, the term 'non-rotational wire rope' is very lax, diameter? number of strands? steel core? galvanized? my guess is that depending on the rope configuration you might have very different behaviours, and even on the same rope configuration, there might be variations between manufacturers.

RE: Help on Torsional stiffness of a non-rotational wire rope

As stated above it varies depending on the category. If your supplier cant or want supply this information I would buy from someone like Bridon.

I think the information your require is here at the Bridon web site.
