                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.

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