Abstract

Ascendant Engineering Solutions (AES) proposes to continue the development of the Large Displacement, Tuned Deck Simulating Fixture for Medium Weight, Shock Isolated Equipment (LTMS) to address the Navy SBIR topic N123-158 - Innovative Approach to Low Cost Shock Testing Fixture for Medium Weight, Shock Isolated Equipment. In the Phase I program, AES developed the LTMS concept with the Large Displacement Mechanism (LDM) to provide the large displacements (greater than the 3 MWSM anvil travel) that produce damage to resiliently-mounted equipment, combined with a Deck Simulating Fixture (DSF) tunable to 8, 14, and 25 Hz. AES completed design trades including linear and nonlinear analyses to verify that the concept was viable. For Phase II, AES proposes to complete the design, fabrication, assembly, integration, tuning and design verification testing of a LTMS prototype on a MWSM. AES will verify operational conformance matching Floating Shock Platform responses for a variety of Class II Equipment configurations and weights. The culmination of this phase will be a qualification test to prove out the LTMS as a viable substitute for some Class II Equipment testing currently relegated to FSP testing.
