FIELD: mechanics. ^ SUBSTANCE: installation for material sample shock loading comprises a base with a pole, a cantilever set on the pole, a tooth gear and a bow set on the cantilever, two toothed racks set on the bow, movable along the latter and connected to the tooth gear, two ram testers fixed on the respective racks, a racks reciprocating movement drive and a table for a sample. The table is mounted on a rigidity regulator made as a set of sequentially and coaxially placed springs of different stiffness with the plates with position latches in respect to the base and the table being put between the springs; the table is set movably along the springs axis and is fitted by a position latch in respect to the base. ^ EFFECT: increased data volume by providing for the tests at regulating the rigidity of the repeated axial impacts. ^ 1 dwg |
