AIRCRAFT SUPPORT EQUIPMENT SHOCK RESPONSE

CURRENT SHIPBOARD AIRCRAFT SUPPORT EQUIPMENT HAS INADEQUATE CAPABILITY TO RESIST EXPECTED SHOCK LEVELS IN HEAVY WEATHER AND COMBAT OPERATIONS. CAREFUL REVIEW OF THE STATE-OF-THE-ART INDICATES THAT MANY CURRENTLY USED PROCEDURES FOR SHOCK RESPONSE PREDICTION OF SHIPBOARD EQUIPMENT AND FOR SHIP GIRDER RESPONSE TO SHOCK LOADS ARE INADEQUATE BECAUSE OF THE MANY ASSUMPTIONS AND THE OVERSIMPLIFIED MODELS WHICH ARE USED. THE ANALYTICAL PROCEDURE PROPOSED HEREIN WILL USE THE NONLINEAR TIME-DOMAIN, 3-DIMENSIONAL ROSAS3 PROGRAM, AND GRILLAGE METHODS, TO PROVIDE ACCURATE PREDICTION OF THE SHOCK LOADS AND SHOCK RESPONSE. THIS PROPOSAL IS INNOVATIVE IN THAT IT WILL APPLY A NEW COMPUTER PROGRAM, ROSAS3, WHICH WILL ENABLE USE OF ADVANCED ANALYTICAL PROCEDURES. NOTE THAT THE GRILLAGE METHOD DOES NOT REDUCE THE DEGREES OF FREEDOM OF THE STRUCTURE, BUT SIMPLIFIES THE PROCESSES OF COMPUTATION BY MATHEMATICAL UNCOUPLING.
