Total deflection less lost motion Procedure The snubber was installed in an MTS load cycling machine and positioned to approximately mid-position of travel.
A linear motion transducer was installed to measure unit travel or displacement."
A load cell was in line with the unit centerline to measure axial load.
Refer to set-up in Photograph 4.
The displacement and axial load were monitored on an oscilloscope with the displacement on the vertical axis and the load on the horizontal axis.
Refer to the photographs on pages 11 thru 14.
The input motion was a displacement that varied as a sine wave which resulted in a load being developed in both tension and compression.
Rated load was applied for 10 seconds at each of the seven frequency steps.

Refer to photograph 5.
The chamber was sealed and a quantity of water was introduced into the chamber.
Heat was applied to the chamber and the temperature was monitored with a thermocouple.
The chamber conditions were ad5usted to 330 F and + 15 psig (Phase I).
0 The air was vented from the chamber which resulted in the units being sub)ected to "all steam".
The temperature was maintained at 330 F minimum and the pressure was allowed to vary between 0 and 15 psig.
The superheated steam condition was obtained by draining water from the chamber in order to keep the pressure from increasing above 15 psig.
A log was maintained of the temperature and pressure.
Refer to pages 1Q thru 21.
