(57) Abstract :
In accordance with the present invention, a simulated crash test system comprises ; a sled trolley, an intrusion actuating mechanism, a
stopping mechanism, a pivoted arms connected to the firewall panel and cross car beam (CCB), wherein said intrusion actuating
mechanism further comprises; plurality of support members rigidly fixed to the sled trolley, a moving plunger actuated by a reaction
pad which is fitted to a rigid wall, when the sled trolley is interacting with said stopping mechanism, said moving plunger is actuated
by the reaction pad. The said moving plunger further actuates pivoted arms connected to the firewall panel & cross car beam (CCB).
Thus when the said sled trolley is being decelerated, the CCB & firewall are intruding in the passenger compartment due to the
plunger movement. The geometrical positioning of plunger, its guide, pendulum pivots controls the level and timings of the intrusions
during a simulated crash test
