A Design and Testing of a Shipborne Severe Impact Test Adjustment Device

TO RESOLVE THE MISMATCH BETWEEN DESIGN SPECIFICATIONS AND TEST INDICATORS IN PENDULUM TESTS FOR ASSESSING THE IMPACT RESISTANCE OF SHIPBORNE ELECTRONIC EQUIPMENT, THIS PAPER DESIGNS A CORE ADJUSTMENT MODULE COMPOSED OF STEEL WIRE ROPE , RUBBER PLATE AND STEEL PLATE, AND CONSTRUCTS A STRONG IMPACT TEST ADJUSTMENT DEVICE BY COMBINING THIS MODULE WITH TRANSITION FRAMES AND CONNECTING PLATES. THROUGH THEORETICAL ANALYSIS, THE NECESSARY STIFFNESS AND DAMPING PARAMETERS REQUIRED TO CONVERT THE PENDULUM TEST IMPACT VALUES INTO TARGET IMPACT VALUES ARE DETERMINED, THEREBY THE STRUCTURAL PARAMETERS OF THE ADJUSTMENT MODULE ARE ESTABLISHED. THE TRANSITION FRAME AND CONNECTING PLATE ENSURE THE ADJUSTMENT MODULE FOR HORIZONTAL AND INCLINED TESTS. EXPERIMENTAL RESULTS FURTHER VALIDATE THE EXCELLENT PERFORMANCE OF THE STRONG IMPACT TEST ADJUSTMENT DEVICE. THE RESEARCH PROVIDES A NEW APPROACH AND TECHNOLOGICAL PATHWAY FOR STRONG IMPACT VERIFICATION TESTS OFSHIPBORNE ELECTRONIC EQUIPMENTAND OFFERS SUPPORT FOR THE VERIFICATION OF SHOCK-RESISTANT STRUCTURAL DESIGNS OF COMPLEX SHIPBORNE ELECTRONIC EQUIPMENT.
