Calc. the deformation of a cable on a reel

[ihaland]

I want to see what effects placing a steel cable on a reel of size of OD 3,51 m will have on the properties of the material?

How will I go about doing this?

A appreciate any help I can get :-)

Not sure what effect you are thinking of. Do you mean memory in the cable? So when it is unreeled what might be expected? S

You need to know the properties of the cable, diameter, number of stands, material.

Utilities use steel or aluminum cable wound on 1 to 3 m reels all the time. I'm not aware of any affects on the material properties.

Well said by PhanthomJay. The material property of interest would be tensile yield strength. ihaland, for your given spool diameter, if we assume this is a 6 x 7 stranded cable (a somewhat coarse construction), then the nominal diameter of your cable could go up to 48 mm before you violate the minimum recommended radius of curvature. And the cable diameter could go even higher if your cable has more strands. Therefore, as PhanthomJay mentioned, you will be OK if your cable is stranded; no problem at all. If your cable is solid, the answer is different. Therefore, we would need to know how many strands are in your cable, and the tensile yield strength of your filament material.

To calculate the deformation of a cable on a reel, we first need to understand the properties of the material. The steel cable is likely to have a certain Young's modulus, which is a measure of its stiffness, and a yield strength, which is the amount of stress the material can withstand before it begins to deform. These properties can be obtained from material data sheets or through experimentation.

Next, we need to determine the dimensions of the cable and the reel. The diameter of the reel, which is given as 3.51 m, is important in determining the amount of bending the cable will experience when placed on the reel. The length of the cable will also affect the amount of deformation, as a longer cable will experience more bending than a shorter one.

Once we have all the necessary information, we can use mathematical equations, such as Euler's beam equation, to calculate the deformation of the cable on the reel. This equation takes into account the properties of the material, the dimensions of the cable and reel, and the applied load (in this case, the weight of the cable). With this equation, we can determine the amount of bending or deflection the cable will experience when placed on the reel.

In addition to calculating the deformation, we can also analyze the stress and strain on the cable. This can help us understand how the material will behave under the applied load and if it is likely to experience any failures or deformations.

In order to accurately calculate the deformation of the cable on the reel, it is important to consider any external factors that may affect the results. For example, friction between the cable and the reel may alter the amount of bending, and the properties of the material may change at different temperatures.

Overall, by understanding the properties of the material, the dimensions of the cable and reel, and using appropriate mathematical equations, we can accurately calculate the deformation of the cable on the reel and analyze its effects on the material. This information can be useful in designing and selecting appropriate materials for various applications.
