Abstract

The invention relates to a technique for dynamic testing of products. The purpose of the invention is to simplify the operation of the installation. This is achieved by using the principle of inductive braking of the moving element of the installation, due to which it is not necessary to adjust the means of braking when testing with different speeds of acceleration of the rolling element. The installation includes a receiver, a barrel in communication with it, including acceleration and brake sections, a clamp to hold the piston located in the barrel in the initial position and means for braking the piston. The latter are made in the form of inductors connected to a source of direct current, covering the trunk brake section, made of a nonmagnetic material. The device for turning on the DC source is interlocked with a lock. The piston is made of a material with 1 electrical resistance or has a ring made of such material fixed on its cylindrical surface. When a piston moves in a magnetic field, inductors in the piston induce currents. The interaction of the fields of these currents and inductors creates a braking force proportional to the speed of the piston. 1 il. (L to aO); o

The invention relates to a testing tester, in particular, to devices for dynamic testing of a product.

The invention is a simplification of plant installation.

The drawing shows the proposed setup for dynamic testing of products.

Installation contains receiver

communicated with him. trunk, including the accelerating section 2 and the brake section 3, piston 4 mounted in the barrel, latch 5 for keeping piston 4 in the initial position, device 6 for transferring the load to the test article (not shown) and means of slowing down piston 4, installed: in the form of inductors 8 connected to the source 7 of direct current, covering the brake section 3 of the barrel. A cylindrical surface of the piston 4 is fixed to a ring 9 made of a material with IHISKIIM e: an electrical resistance, or the piston 4 is made of such a material. The brake brake stem 3 has a hole 10, and in its Koin.i, e, buffer devices 11 are installed, the loaded rods 12 of which, when coupled with the piston 4, can move with in direction, perpendicular to the smallpox of the trunk. Fgnssator 5 sblokty.yuavi. with

the device 13 for turning on the ICTO IIA 7 of direct current, to which the inductors 8 are connected. The brake section 3 is closed by a cover 14 with a hole 15.

The proposed setup for dynamic test products works as follows.

Before the pressure in the receiver 1, the necessary pressure is created. After that, the latch 5 and the device which is locked with it are turned on to turn on the source 7 of the direct current, and the coils of the inductors 8 are energized. 6. After this, continuing its movement, the piston 4 enters the brake section 3 of the barrel, where it takes, together with the magnetic field, the inductors with the magnetic field. 8. At the same time, in the piston 4 of the Yochi ring 9 are driven

Prince The magnetic field induced by these currents interacts with the magnetic field of the inductors 8, as a result of which the pistol 4 slows down. At the end 5 of the brake section 3 of the barrel, the piston 4 is finally stopped by the buffer device 11. The gas contained in the receiver 1, when the piston 4 is moved, leaves through the openings 10 into the atmosphere, shortening the braking path of the piston 4.

At the end of braking, the piston 4, at the moment of its complete stop, stops, with the induction of a magnetic field).) The ring 9 of the piston 4 and the braking force becomes zero.

Consequently, when the installation is in operation, the piston cannot rebound. The piston 4 tilts easily by pre2Q by creating a magnetic field that guarantees braking of the piston 4 along the length of the brake section 3 of the barrel.

25 Thus, a special adjustment of the braking means is not required depending on the mass and speed of the piston 4, which makes it easier to operate the plants.
