stiffness damping 求教

ARMATURE_4438 = 0.008419
ARMATURE_5047 = 0.044277
ARMATURE_6056 = 0.066666

NATURAL_FREQ = 10 * 2.0 * 3.1415926535  # 10Hz
DAMPING_RATIO = 2.0

STIFFNESS_4438 = 50
STIFFNESS_5047 = 65
STIFFNESS_6056 = 80

DAMPING_4438 = 1.1
DAMPING_5047 = 1.5
DAMPING_6056 = 1.1
机器人配置这个怎么算的呢 前后  ARMATURE_4438*NATURAL_FREQ^2 与STIFFNESS_4438 差得挺大的，求教
