Frictional Heat
1 Attachment(s)
Hi Guys,
I'm currently trying to set up a model in WB, where a frictional contact between two parts produces heat and thus the temperature in the parts changes over time. I started with an Transient-Structural-Analysis and connected it via APDL commands with a thermal analysis. I followed the steps in this video https://www.youtube.com/watch?v=IbKEMAbJx6U and this video https://www.youtube.com/watch?v=p6IoDlNz5GU My commands look like this: Geometry/Body: et, matid+5, 223, 11 Contact: keyopt, cid, 1, 1 rmodif, cid, 15, 1 rmodif, cid, 18, 0.5 keyopt, cid, 10, 2 keyopt, cid, 9, 1 r, cid, 1e-3, 0.1 rmodif, cid, 14, 1e4 Analysis: tref, 23 cmsel, s, bot d, all, temp, 23 allsel, all Although I set the reference temperatur to 23°C my solution looks like in the attached picture. Almost all elements have an initial temperature of 0°C. Now I'm not sure what I did wrong with my model because I followed all the instructions from the videos. If anyone got ideas or thoughts on my problem I'd be thankful. :) |
