How get total belt length in Simscape multibody belt-cable system

I'm using the 'Belts and cables' library in Simscape Multibody. My overall setup consists of a Spool at both ends of the belt with several pulleys in between. Is there a built-in manner of determining the total length of the belt from spool to spool?

Hi Bart,

I understand that you are trying to calculate the length of belt/cable from spool to spool.

Unfortunately there is no such built-in function which can directly determine the length of cable between the spools. However a custom MATLAB function can be written to calculate the same.

Here are certain assumptions based on the description:

• Firstly the distance between the spools is known.
• We know the radius of spool.

You can refer the following code and can modify it according to the use-case:

function calculateLength()
   windings1 = n1; %number of times cable is wound on spool 1
   windings2 = n2; %number of times cable is wound on spool 2
   circumference1 = 2*pi*r1;
   circumference2 = 2*pi*r2;
   totalLength = (winding1)*2*pi*r1 + (winding2)*2*pi*r2 + d;
end

hello .

I have a question . can i measure length of belt-cable end ?
