METHOD AND STAND FOR MODELING BIAXIAL SHOCK LOAD TO TEST OBJECT Russian patent published in 2019 - IPC G01M7/08 

FIELD: test.

SUBSTANCE: invention relates to a testing technique and can be used to dynamically test objects for the effects of shock overloads in two directions simultaneously. Technical result is achieved by the fact that in a test bench for simulating a shock load on a test object, containing an external shock formation unit, a container in the form of a hollow piston and a table designed to secure the test object, the table is placed in a container with the possibility of plane-parallel movement along its longitudinal and transverse axes and is connected to the container through a connection, which is made in the form of two or more guide elements. Technical result is also achieved by applying a method for simulating a shock load on the test object in two mutually perpendicular directions, characterized by the fact that the overall characteristics of the connection are chosen, table is located in connection with the possibility of plane-parallel movement thereof, the connection in the form of guide elements is placed, the amount of deviation of the connection is chosen from the equilibrium position, the table with the test object fixed thereon is installed coaxially with the container for communication, consisting of guide elements providing plane-parallel movement, an external impact is carried out on the container, the test object and the table are moved along the container in a plane-parallel manner relative to the container to the equilibrium position.

EFFECT: technical result is to provide a biaxial loading mode of an object with a given level of parameters (amplitude and duration of shock acceleration) of a shock pulse in two mutually perpendicular directions (for example, in the longitudinal and transverse directions) and a decrease in the number of tests.
