Secure for Sea with

BLISS SHOCK CORD

Heavy duty Bliss Shock Cords absorb strain. Top- side and below decks, strong-Shock Cord (multiple rubber strands encased in one or two braided covers) keep taut cargo, gear, equipment, furniture; canvas^ covers, all types and sizes. Shock Cord tie-downs stay taut under ordinary strain, expand'to meet sudden extremes of wind, sea, rain, then instantly contract to original tautness. Far superior for fast tie-down and release to metal and leather strapping and rope. Made to definite standards for tension, stretch, break, abrasion resistance. to 1", single and double covered. Cotton and Nylon. Keep reds aboard. Unroll as needed, as easily as rope.

Shock Analysis Methods

Discussed At Meeting Of

SNAME Philadelphia Section

Principals of the Philadelphia Section meeting, left to right: Section chairman Thomas J. Kavanagh; authors

Brian C. McNaight, Robert P. Brooks, and Neil Goodis, and meeting coordinator Capt. J.M. Dunford, USN (ret.).

On the evening of March 15, the Philadelphia

Section of The Society of Naval Architects and

Marine Engineers gathered at the Engineers'

Club in Philadelphia to hear the presentation of "Simulation of Shock Platform Tests—A

Design Tool." Robert P. Brooks, Neil Goodis, and Brian C. McNaight, all of the Naval Air

Engineering Center, Philadelphia, reported on their successful efforts to mathematically model the physical reactions of equipment to shock tests performed on floating shock test platforms. A film, "Shock Test of Heavy

Equipment," gave the audience an understand- ing of the physical situation which the authors sought to model. In their verbal presentation of their work, the authors described how finite difference techniques were applied to a spring- mass model of an A4C aircraft mounted on the Navy's Mjedium Shock Test Platform.

Using this method, the authors obtained re- sults which were very close to the results of the actual test.

In commenting on the paper, David Hirt,

NAVSEC Headquarters, said that most ana- lytical methods for shock analysis either in- volve approximations or are based on tests of particular equipment and are not generally ap- plicable to other type's of equipment.' The shock analysis method developed iby the au- thors applies the basic law's of physics to the problem and is more flexible than earlier methods.

The authors' mathematical model of the floating shock test platform allows equipment vendors who mu'st meet Navy shock specifica- tions to simulate on a computer the actual shock test of their equipment. The results of the computer test allow the equipment vendor to identify and correct any weaknesses in the equipment prior to the physical test on the shock test facility.

Section chairman T.J. Kavanagh o'f the

Philadelphia 'Naval Shipyard conducted the meeting, which was coordinated by Capt. J.M.

Dunford, USN (ret.), formerly with the Na- val Air Engineering Center, Philadelphia, and currently with" GDI, Inc. in Jacksonville, Fla. iBIl ^BHIIWffcaB
