Abstract
A translation control and rotation control mechanism support jig for supporting a front end portion of an automobile body part includes a pair of support members, a rotary box having an L-shaped plate, a rotary shaft pin, a compression pin, and a connection plate. The translation control mechanism includes a support plate, a slide guide, an automobile body part securing disk, a translation plate, and a compression pin. Energy-absorbing members are disposed in an arcuate guide groove on a side surface of the rotary box and a linear guide groove arranged on the support plate or the translation plate. A collision punch collides at a test speed with the L-shaped plate of the rotary box. The compression pin deforms the energy-absorbing members to apply torque opposite to a rotation direction and a reaction force in an opposite direction to a translation direction.
