Specifications include, but are not limited to: A. Module 1 - Part #1-Reaction mass crash system backing plate a. Metal Plates to be mounted on the walls of the concrete reaction mass at the four corners of the table (platen) to absorb energy from any uncontrolled table movement via the crash system absorption device hitting this plate. Four plates required. ; Module 2 - Part #2-Reaction mass crash system lining plate a. Sacrificial wear Plates to be mounted on the surface of the Metal Plates at the four corners of the table (platen) to absorb energy from any uncontrolled table movement via the crash system absorption device hitting this plate. Four plates required. b. Fabrication Duration: Two (2) – months after award notification. C. Module 3A - Part #3-100482285 PLATE - MOUNTING, HORIZONTAL ACTUATOR a. Metal Plate assembly mounted on the wall of the concrete reaction mass to allow pinned connection of the horizontal actuators which provide for “X” & “Y” table direction movement along with factoring into “Yaw”, “Pitch”, and “Roll” thru computer control. UCSD is planning on re-using two existing Part #3 mounting plates with modification – Module 3A to include two (2) Part #3 plates. b. Fabrication Duration: Two (2) – months after award notification.
