Damping matrix for ross.ShaftElement and ross.ShaftElement6DoF #967
-
|
Hi, thank you very much for this Python package, it is very useful. However, I have a question about the damping matrix in 'ross.ShaftElement' and 'ross.ShaftElement6DoF'. Why is there no consideration of internal damping in the shaft in 'ross.ShaftElement' (C = np.zeros((8, 8))) while 'ross.ShaftElement6DoF' considers internal damping in the shaft (C = self.alpha * self.M() + self.beta * self.K())? |
Beta Was this translation helpful? Give feedback.

Hi @TeinIHuang! The 4 dof has been implemented first, and then we had different people implementing the 6 dof and they decided to consider the internal damping. In the future, we wish to solve this by making the 6 dof element the ‘default’, but for know we have this difference between them because of a lack of time for developers to standardize that. |

Hi @TeinIHuang!
There is actually no good reason for that...
