Belt Wear Validation - Post graduate Thesis

Hello dear all,

I will really appreciate your comments and ideas for my Belt Wear Validation Strategy.

I would like to present a belt wear validation based on the Hertz-Mindlin Archard Wear equation after a simulation with EDEM.

As I am not allowed to go into the mine, I just know that the belt (8,720 m) has a 3mm anual wear depth.

I also leave an screenshot, there is the figure 23. just to be 100% sure, is it the right way to calculate the wear K parameter?

It will be possible? are there a better way to validate the EDEM results? where can I start? Could you please share with me some aditional info?

Best regards,

Hi José,

Assuming that you already have calibrated the contact parameters, what I'd suggest you do is:

Run a simulation with an initial guess of the wear constant until you reach steady state
Get the wear depth of your simulation
Compare the results you got in step 2 with the actual estimated wear depth for that same amount of time. You know that in one year the wear depth is 3 mm so based on the you can estimate the wear depth in, let's say, 60 seconds.
If the results from step 2 and step 3 are the same or pretty close you've found the wear constant. Otherwise, go back to step 1 and change the value of the wear constant. Repeat as many times as needed

Hope this helps you.

Best regards,

Renan
