BLOCK 3-DATA DESCRIPTION:

The Dynamic Shock Analysis Report shall contain the following information:

  1. A printout of the input data used in the analysis. This data shall include all nodal point locations, element connectivity, material properties, element properties and mass distribution. This data shall be in agreement with data provided in the Dynamic Shock Analysis Mathematical Model Report, Data Item No. A121.
  2. The frequency, modal effective weight, shock input and participation factor for each mode considered in the stress and deflection calculations. Additionally, mode shapes, and associated forces and deflections shall be included in the report.
  3. Calculations for stresses and deflections at those specific areas of concern of the equipment or structure under shock loading, as defined in the Mathematical Model Report. References to the source of data used in these calculations shall be provided. Drawings which aid in an independent review of the calculations shall also be included. If no drawings are available, sketches shall be provided.
  4. Tabulated summaries of calculated and allowable stresses and deflections. These summaries shall include the sources of the tabulated stresses and deflections, such as tensile, shear, and operating loads.
  5. A comprehensive analysis of the foundation, when the foundation is supplied by the equipment vendor. When the foundation is provided by the shipbuilder, the vendor shall provide a summary of the shock forces into the foundation for use by the shipbuilder in his analysis.

BLOCK 4-REVIEW REQ.:

Government approval required for technical content. Allow 45 days for Government review and comment.

BLOCK 5-SUBMITTAL SCHEDULE:

20 days after dynamic shock analysis; R/ASR 20 DARC. Revisions shall incorporate Government comments.
