Rotary spring damper#

Rotary spring damper block simulates the presence of elastic link and friction between shaft ports (1):

(1)#\[\begin{split} T = K\cdot\int\Delta\omega dt+D\cdot\Delta\omega\\ \Delta\omega=\left(\omega_1-\omega_2\right) \end{split}\]

where

\(K\) – coefficient elastic of shaft, [\(\frac{N\cdot m}{rad}\)];

\(D\) – friction ratio, [\(\frac{N\cdot m\cdot s}{rad}\)];

\(T\) – shaft force moment, [\(N\cdot m\)];

\(\omega_1\) – first shaft angle rate, [\(\frac{rad}{s}\)];

\(\omega_2\) – second shaft angle rate, [\(\frac{rad}{s}\)].
