PENDULUM TESTS ON TRANSFORMER BASES FOR LUMINAIRE SUPPORTS

Energy absorbing characteristics of four cast aluminum transformer bases for luminaire supports were determined using a 2000 lb pendulum. Complete luminaire supports including the base, pole, mast arm, and simulated luminaire were tested. Velocity of the pendulum at impact was 20 mph. High-speed photography was used as the primary source of data acquisition. Change in momentum of the pendulum during impact was used to characterize the behavior of the bases. Details of the data analysis procedure and their influence on the results are discussed. /FHWA/
