Description

t1307291

The invention relates to the study of the strength properties of materials, in particular, to devices for dynamic testing.

The C & P of the invention is an increase in the information content of the tests and a reduction in labor costs during the tests. This goal is achieved by inserting the X-ray pulse registration system rigidly on a rotating camera into the device of the photo recorder and the axis of rotation coincides with the optical axis of the photo recorder, which leads to the placement of the place interoperable

of the 3 and the trajectory of the impact, the nick is rotated in the supports 8 on the bearings 7 to the corresponding y. Together with the camera 1, the X-ray machines 5, X-ray cassettes 4, system 11 sub sample 3 are rotated. When the camera rotates, the impact site of the sample 3 remains in The field of view of the photostrake 10 and the X-ray pulsed registration system, which excludes their setting. The drummer enters chamber 1 through a slit-like hole and interacts with sample 3, which

Lo in the field of view of recorders.

The drawing shows the device, a section along the axis of rotation of the camera.

The device comprises a chamber 1 s behind the device 2 fastened therein for fastening the test sample 3, an X-ray pulsed recording system consisting of two X-ray cassettes 4/4 placed in the chamber 1 and two X-ray machines 5 installed outside the chamber 5. The camera 1 is attached to the inner rings 6 bearings 7, which is a part of the mechanism for setting the angle between the normal to the surface of sample 3 and the trajectory of the impactor (not shown). The camera 1 with the help of bearings 7 has the ability to turn on the supports 8. The axis of rotation of the camera 1 is horizontal and intersects the path of the striker at a right angle. In the side of camera 1, there is a window 9 combined with the inner ring 6 of one of the supports 7. The high-speed photo recorder 10 is located opposite the window 9, its optical axis is aligned with the axis of rotation of the camera 1. The illumination system 11 of sample 3 is placed inside

stratome 10 on the film and the X-ray pulse registration system. This increases the information content of the test. For the next test, a new sample 3 is fixed; if necessary, turning the chamber 1 establishes a new angle between the normal to the surface of the test sample 3 and the trajectory of the striker and performs a test. Excluding the settings of the photographic recorder 10 and the X-ray pulse recording system between tests reduces labor costs during the tests.
