ABSTRACT:
A test fixture for rollover crash testing of a test vehicle onto a movable sled surface employs a cradle to support and rotate the test vehicle. A suspension assembly is attached to each end of the cradle for vertically supporting and dropping the cradle. A gantry has a cross beam supported by a first telescoping column for support of a first of the suspension assemblies and translationally supported by a second telescoping column for support of a second of the suspension assemblies to position and releasably hold the suspension assembly. Roll control arms rotate the cradle and a trigger assembly releases the cradle and test vehicle from the cross beam for contact within a drop impact zone on the contact surface of the sled. A brake assembly then arrests vertical motion of the cradle.
