阻尼力矩计算方法
铰链阻尼力矩 T=K(Tg+Tw） (K为安全系数；Tg为克服重力力矩；Tw为克服风阻力矩）
Tg=GL=mgL=0.44X10X0.1=0.44N.m(G为维护腔盖重量；L为维护腔重心与阻尼铰链轴心间距离)
Tw=0.65AV2L （A为维护腔盖上表面积；V为6级风速）
T= K(Tg+Tw）=K[0.44X10X0.105+0.65*(0.21*0.07)*13.82 *0.105]=0.68K(N.m)
当K=2时；Tmin=1.36N.m;

Figure7 Side thrust force (F1，F2)and Maximum spacing destructive force(F3) test
Calculating Damp Torque
Damp hinge torque T = K (Tg + Tw) (K indicates the safety coefficient; Tg indicates the torque for overcoming the pull of gravity; Tw indicates the torque for overcoming the force of the wind)
Tg = GL = mgL = 0.56 x 10 x 0.1 = 0.56 N.m (G indicates the weight of the maintenance cavity; L indicates the distance between the gravity center of the maintenance cavity and the damp hinge axis center)
Tw = 0.65 AV2L (A indicates the area of the maintenance cavity cover; V indicates level 7 wind speed)
T= K (Tg +T w) = K [0.56 x 10 x 0.1 + 0.65 x (0.2 x 0.083) x 17.12 x 0.1] = 0 .88 K (N.m)
If K is equal to 2, Tmin is 1.76 N.m (15.58 lbf.in.).
