DYNAMIC TEST BENCH Russian patent published in 2012 - IPC G01M7/08 

FIELD: test equipment.

SUBSTANCE: invention refers to test equipment and can be used for investigation of resistance of various items, their assemblies and instruments to the impact of pulse inertia loads. The bench includes a base on which upper and lower rail guides, acceleration device including a shaft and a pressure source and installed on lower guide with possibility of being moved along it, and container for the test item, are fixed. Container includes a rear end entering the shaft and is provided with possibility of being moved along upper and lower guides. Symmetry planes of guides are located in vertical plane passing through the shaft axis. Dynamic test bench is equipped with a piston installed in the shaft after the container and tightly connected to its rear end, and made of material with lower density in comparison to container rear end. Piston rear end can be made at an angle to the shaft axis, which differs from 90°, in movement direction.

EFFECT: possibility of performing the test in wide range of duration of inertia pulse loads applied to the test item is provided.
