Shock Test Program. Shock Isolation Design Manual for SAFEGUARD TSE Systems and Equipment

摘要

The report contains 4 parts. Part I, Design and Theoretical Considerations, Part II, User's Instructions for Computer Program, Part III Program Listings for both ISIP (Integrated Shock Isolation Program) and ISIP2, and Part IV, examples. ISIP is formulated on the basis of considering the shock isolation platform and the equipment on it as a rigid body six-degree of freedom system having large response amplitudes. ISIP2 includes a treatment of shock isolation systems having relatively flexible platforms. Both ISIP and ISIP2 accept acceleration-time history excitation. For the shock isolation systems the excitation of which is given in terms of a shock spectrum, a synthesized acceleration time function must be obtained as the first step toward problem solution. Waveform Synthesis is performed by WAVSYN which is a subprogram of ISIP and ISIP2. The design parameters and their interrelationships which affect the performance of a shock isolation system are discussed, and several design configurations and various elastic and dissipative elements in shock isolation systems are investigated. Analytical treatments of the problem, which forms the basis of computational procedures, are included. The report is organized for the convenience of practicing engineers who have had previous exposures to rigid body mechanics, structural dynamics and the Fortran language. (Author)
