<damping_coeff> and <damping_coeff_rebound> set the damping coefficient on compression and rebound, respectively. If <damping_coeff_rebound> is omitted, the rebound coefficient defaults to the same as the damping_coeff. | The parameters <damping_coeff> and <damping_coeff_rebound> set the damping coefficient on compression and rebound, respectively. If <damping_coeff_rebound> is omitted, the rebound coefficient defaults to the same as the <damping_coeff>. | ||
<damping_coeff> and <damping_coeff_rebound> parameters can be set to use either linear or square damping. The default is linear (damping proportional to the velocity of the compression or rebound). | The <damping_coeff> and <damping_coeff_rebound> parameters can be set to use either linear or square damping. The default is linear (damping proportional to the velocity of the compression or rebound). Use 'type="SQUARE"' to specify square damping (damping proportional to the square of velocity of the compression or rebound). | ||
If linear, units are LBS/FT/SEC or N/M/SEC. If square, units are LBS/FT2/SEC2 | If linear, units are LBS/FT/SEC or N/M/SEC. If square, units are LBS/FT2/SEC2 or N/M2/SEC2. | ||
Using square damping should result in more vigorous damping under extreme forces and accelerations and may help reduce extreme ground reaction forces sometimes experienced under JSBSim. | Using square damping should result in more vigorous damping under extreme forces and accelerations and its use, especially for <damping_coeff_rebound>, may help reduce extreme ground reaction forces sometimes experienced under JSBSim. | ||
