Vacuum lines on the motion table are routed through the table using rotary joints. Simultaneous motion and vacuum testing is accomplished through the use of a vacuum pump attached to the base of the table system and a vacuum bell jar attached to the tabletop. Installing a vacuum system on a motion table exposes articles under test to vacuum while the table is responding to motion stimuli. Motion table vacuum lines originate at fittings on the tabletop, are routed through vacuum rotary joints and terminate in fittings secured to the table bases. Vacuum pumps and attached digital vacuum gauges are each plugged into standard 115 VAC outlets.
Vacuum chambers consist of a base plate and a bell jar housing.
Base plates bolt onto the rotating tabletops and contain a threaded hole pattern for securing the unit under test. Manual shut off valves, electrical feed thru connectors, and the vacuum connection are located in the top of the bell jar housing that bolts to the base plate. An 18 inch long flexible vacuum hose is installed between the bell jar housing and the fitting on the tabletop. Ideal Aerosmith's standard vacuum system will create a vacuum level of 10 milli-torr in the vacuum chamber. Customer specified test article mounting hole pattern within vacuum chamber.
