Energetic Regularities of Pulse Loading by Systems With Intermediate Link

Abstract

The investigations carried out deal with the re-gularity study in the distribution of shock pulse energy at multiple procedures of loading. The experimental researches were carried out on the specially developed test bench in which under all waveguides (or tools) of the shock system there were situated independently (separately) sensors connected with an oscilloscope registering parameters of a shock pulse (a form, amplitude, duration).
 As a result it was determined that the increase of the eccentricity in the symmetry axis location of a head and a waveguide (or a tool) and their number in the shock system contributes to the reduction of an energy portion sent to the deformation source. The application of multi-contact schemes of loading allows sending large total energy of a shock pulse to the deformation source to accept conditions of experiment fulfillment.
 At that the energy portion of a shock pulse fall-ing to each waveguide (or a tool) in the multicontact scheme as compared with the singlecontact one decreases (for rod-formed waveguides by 20%, and for spherical tools – by 15%) at the installation of each subsequent waveguide (or a tool) in the shock system.
