    Vibration simulation

    Analysis purposes

    1. By vibration simulation analysis, we can get the stress and the highest of stress speed of each part.

    2. Then, unified computing with the fatigue life of the material, we can judge if the chosen material is qualified to the resistance requirements.

    Analytical conditions

    Vibration Frequency(Z) Power Density Spectrum
    10 0.208
    55 0.0677
    180 0.0026
    300 0.0026
    360 0.00146
    1000 0.00146

    3σ(1.86) 3.79E13 7.93E6 2.08E-07
    Reflector 1σ(1.84) 4.66E19 4.86E7 1.04E-12 2.13E-08
    2σ(3.68) 1.61E16 2.11E6 1.30E-09
    3σ(5.52) 1.52E14 3.06E6 1.99E-08

    The total damage of reflector , housing , lens is less than 1, so the fatigue damage will not happen
