La structure principale de ladite table est constituée d'un corps de table (3), d'une poutre (2), de deux trumeaux ajustables (1) et d'un portique de simulation (4). La structure principale possède une structure symétrique, les deux trumeaux ajustables (1) étant fixés de manière symétrique sur les bords de deux côtés du corps de table (3). Le portique de simulation (4) est fixé sur la poutre (2) par une charnière de véhicule (10), et un vérin pneumatique de mise en tension (6), une poulie (9) et un vérin pneumatique de levage (11) sont placés sur la ligne de symétrie centrale du plan de corps de table (3). Pendant le test, il faut fixer séparément les deux extrémités d'un ensemble formant ressort pneumatique (5) sur l'extrémité supérieure du trumeau ajustable (1) et le portique de simulation (4) ; parvenir à la plage de déplacement normal du ressort pneumatique en ajustant les positions de fixation des trumeaux ajustables et du portique de simulation (4) sur lesquels l'ensemble formant ressort pneumatique (5) est fixé ; et commander le levage et la compression de l'ensemble formant ressort pneumatique (5) par l'intermédiaire du signal correspondant provenant d'un boîtier de commande électronique programmable.
