METHOD AND RIG FOR MODELLING OF IMPACT LOAD ON TESTED SUBJECT

摘要

FIELD: test engineering.;SUBSTANCE: rig contains the external impact-generating unit, container in the form of a hollow piston, and table designed for securing of a test subject, located in the container with the possibility of movement along its longitudinal axis and connected to the container by means of a flexible coupling. The flexible coupling is performed in the form of a set of flexible rings located successively and coaxially to the longitudinal axis of the container with the possibility of deformation in radial direction and contacting each other by the plain surface, and an insert in the form of a hard ring nested in the utmost ring of the flexible rings.;EFFECT: provision of modelling of required parameters of an impact impulse, transformation of vibrations of the impact impulse into a positive term single impact action, and decreasing of the device dimensions.;3 cl, 3 dwg
