DEVICE FOR TESTING MATERIALS FOR STRENGTH Russian patent published in 2014 - IPC G01N3/18 

FIELD: testing technology.

SUBSTANCE: invention relates to testing technology and can be used to test the material samples for strength. Essence: the device comprises a base (1) on which the grippers (2, 3) for the sample (4) are mounted, a loader (5) connected to the gripper (2, 3), a device for heating a in the form of a heat conducting ring (6) for securing the sample (4) on the surface, a friction element (7) intended to interact with the outer surface of the ring (6), a device for pressing the friction element (7) to the ring (6) with an elastic element (8) and a regulator (9) of deformation of the elastic element (8), the device for moving the friction element (7) relative to the ring (6) with a platform (10) and a rotary drive (11) with a shaft (12). In addition the device is equipped with additional devices (13) for heating in accordance with the number of zones of the thermal load and their locations along the length of the sample (4). At that each device (13) for heating is provided with a pulley (14) mounted on the shaft (12) of the corresponding rotary drive (11). The friction elements (7) are made endless flexible and cover the pulleys (14) to ensure interaction without slipping and the rings (6, 13) to ensure interaction with slipping. The drives (11) are mounted on the platforms (10). The elastic elements (8) and the regulators (9) of deformation of the elastic elements (8) connect the platforms (10) with the base (1). The loader (5) is made in the form of a press for mechanical sample loading (4).

EFFECT: expansion of the amount of the information obtained.
