Section 1

1.1 Background: West Desert Test Center (WDTC) Has procured a new 3-inch displacement multi-shaker vibration system that can be coupled together and used as one system in both the vertical or horizontal positions or it can be separated and used as two different systems in both the vertical and horizontal positions. An environmental chamber box (ECB) is required to be placed around the test items during vibration testing in both vertical and horizontal positions and in both configurations (coupled together or separated). The ECB will need to be reconfigured to support the new vibration system in six different positions. i.e. lift and right single separated vibration systems in both the vertical and horizontal positions and copulated together in both vertical and horizontal positions.

1.2 Description: WDTC has a 2-inch displacement vibration system that can be operated in both the vertical and horizontal positions. When this vibration system is operated an ECB is placed over the test item and the ECB is connected to an environmental conditioning system, which provides hot, cold, and humidity conditions as required, to the ECB. The connection is made with 18–inch diameter ductwork with 4-inchs of foam insulation between the inside and outside metal ductwork. The sections of insulated ductwork are connected from the main ductwork to the ECB by way of transitioning ductwork that is constructed of the type of material as the main ductwork. The floor of the ECB can be configured to fit around the vibration head expander, when in the vertical position, with no more than a 1 to 1 ½ inch gap between the opining in the ECB floor and the head expander. This configuration provides 2 –inch of free movement of the vibration head expander in the vertical direction. The ECB can be reconfigured to provide the same type of coverage in the horizontal position. This accomplished by removing a section of the flooring of the ECB and replacing it with a differently configured floor section. However, the gap between the front and back of the slip table and the floor of the ECB is about 2 to 2 ½ inch to allow for the 2-inch displacement movement of the slip table. A different insulated transition ductwork is all so required for this configuration. The ECB is supported with a network of scaffolding that can be configured to support the ECB in the vertical or horizontal position. However, this 2-inch displacement vibration system is being replaced with a new Multi-Shaker 3-inch displacement vibration system that is comprised of two separate vibration systems that can be operated separately or coupled together to function as one larger vibration system. The ECB that is used on the old vibration system will be reconfigured to operate with the new Multi-Shaker vibration system. The new vibration system will be located on a different reaction mass located in the same building as the old vibration system that the ECB is now operated on.

1.3 Objective: The objective of this document is to provide the specification, basic layouts, and requirements for the reconfiguration of the ECB floor, ductwork, and support structure. It is all so the objective to utilize the same installed environmental conditioning system and ductwork that is used to connect the environmental conditioning unit to the main transitioning connection point located in building 3133. It is all so an objective to ensure that the same air flow to the ECB is the same after reconfiguration is completed as it is in the present configuration.

Section 2

NOTE: None of the ductwork, floor inserts, or support structure can interfere with the operation of the multi-shaker vibration system and any of the six (6) different positions.
