    阻尼力矩計算方法

    鉸鏈阻尼力矩 T=K(Tg+Tw (K為安全系數;Tg為克服重力力矩;Tw為克服風阻力矩)

    Tg=GL=mgL=0.44X10X0.1=0.44N.m(G為維護腔蓋重量;L為維護腔重心與阻尼鉸鏈軸心間距離)

    Tw=0.65AV2L  A為維護腔蓋上表面積;V6級風速)

    T= K(Tg+Tw=K[0.44X10X0.105+0.65*(0.21*0.07)*13.82 *0.105]=0.68K(N.m)

    Maximum spacing destructive force

    Secure the damp hinge support. Use the test tools to exert the force see F3 in appendix Bof 249 N (56.025 lbf) at the position 185 mm (7.28 in.) away from the axis center, and keep the force 5 seconds.

    After the force is released, the hinge spacing does not fail,

     and the damp hinge axis can be rotated with the turning angel range 0° to 150°

    Surface quality requirements

    Surface quality requirements

    Perform the steady salt spray test specified in GB/T2423.4 for 30 days on each component.

    No red rust or white powder is found on the surface of the sample, and no corrosion such as stress corrosion, crack, spot, or scratch is detected.

    2. Non-metal samples or materials do not deteriorate.

     

     

    Perform the cyclic salt spray test specified in GB/T2423.4 for 10 days on hinge components.

     

    Test the paint coating based on Huawei RF module coating adhesion force test standards.

    No coating fall-off occurs.

    Reliability

    Service life

    Open and close each damp hinge 200 times at the frequency of 8 to 10 times per minute.

    Damp hinges work properly, no obvious power crumb is found, and the damp torque change is less than ±20%.

    Mechanical properties after the salt spray test

    Perform the cyclic salt spray test specified in GB/T2423.4 for 10 days.

    The damp torque change is less than ±20%.

    Dust inhalation test

    Test damp hinges by complying with the IP5X standard.

    Damp hinges work properly, and the damp torque change is less than ±20%.

    Falling test

    Perform the falling test on the packaged entire system by complying with Huawei falling test standard. This test is not applicable to components.

    The damp torque change is less than ±20%.

    No loosen component or potential loosen risk is found.

    Flame spread rating

    Test the flame spread rating of non-metal components by complying with the UL94 standard.

    The test results meet the requirements described in the HB standard.
