Torque tests of a full size model of the Alvin/AUTEC emergency sphere release
MetadataShow full item record
Laboratory torque tests were perfoirmed using an actual emergency sphere release shaft of the type used in the research submarines ALVIN, SEA CLIFF and TURTLE. A test fixture was constructed which permitted laboratory simulation of the side (squeezing) forces applied to the release shaft came as a result of forebody buoyancy. Estimated full-scale side forces were applied to the cam by a laboratory compression testing machine, and the torque required to rotate the shaft was measured. Tests were run with contacting surfaces (a) clean and dry, (b) greased, and (c) immersed in sea water. From the test results, values of release torque were calculated for the submarines in question. Coefficient of friction values of the contrating materials (Monel K-500 on phosphor bronze) also are reported.

Experimental stress analysis of model of emergency forebody release device used in deep diving research submarines Alvin, Sea Cliff and Turtle Sharp, Arnold G.; Sullivan, James R. (Woods Hole Oceanographic Institution, 1969-08)Tests were conducted on a full-scale model of the emergency forebody release used in the deep-diving submarines ALVIN, SEA CLIFF and TURTLE. The model was machined from metal to the same dimensional tolerances as the ...
Mavor, James W.; Sharp, Arnold G. (Woods Hole Oceanographic Institution, 1965-08)The emergency hull release of ALVIN was redesigned in an effort to reduce shaft bending stress and to eliminate galling of contacting surfaces. new design features quarter-turn cam on unthreaded shaft instead of eight-turn ...
