damping_coeff and damping_coeff_rebound control 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> 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 control can be either linear (default) or square. If 'type="SQUARE"' is omitted they default to linear.  If linear, units are LBS/FT/SEC or N/M/SEC.  If square, units are LBS/FT2/SEC2 | 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.
<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 | 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.
