The integrated design of solar street lamp pole and battery module has strong wind resistance, but how do we calculate the wind resistance of solar street lamp pole?
1. Calculation of the windward area of the solar street lamp pole panel (including lamps): because the lamp panel adopts different shapes, the windward area of the lamp panel is uncertain. Take the common closed saucer shaped lamp panel as an example, and take the frontal projection of the lamp panel shape as the windward reference area S lamp panel=(d1+d2) H1/2.
2. Calculate the windward area of the solar street lamp pole body: the pole body of the high pole lamp usually adopts a cone or cylinder (with a taper of about 1000:5). The windward area of the rod increases with the increase of the rod length. S Rod body=(D1+D2) H2/2. Recommended reading: LED street lamp life detection method
3. Basic wind pressure calculation of solar street lamp pole. The wind pressure is the wind pressure on the plane perpendicular to the airflow direction. The standard wind pressure relationship formula is obtained according to Bernoulli equation. The dynamic pressure of wind is: WP=0.5 * r * V2/g=0.5 * ro * V2 (ro=r/g) WP is the wind pressure, in KN/M2. Ro is the air density, in KG/m3. V is the wind speed in M/S. R is the air density, in KN/M3.
