Abstract

SUBSTANCE: carriage 4 for supporting test article 5 is freely supported on an additional carriage 8 and is discarded together with it and anvil 6. Anvil is mounted on carriage 8 through gaskets 12, which serve to adjust the gap between it and carriage 4, and can move relative to carriage 8 when collision with elastic base 9 and inflict a counter strike on the product when bouncing. Due to the free support of the carriage 4 on the carriage 8, the mass of the latter does not affect the impact, therefore, the amplitude of the shock impulse imparted to the product can be increased. 1 ill.

Description

At ///////////////////// / K /.

 / (The invention relates to a testing technique, namely to impact test benches.

The purpose of the invention is the expansion of the operational capabilities of the bench by increasing the shock pulse communicated by the carriage with the test product.

HP drawing shows the proposed stand.

The stand contains a frame 1, a power frame 2 fixed with it with cable -way guides 3, mounted with cable guides 3 carriage 4, for placing test article 5 on it, anvil b, the brake device is placed between the anvil 6 and carriage 4 7, an additional carriage 8 installed in the guides 3, on which the carriage 4 with the test article 5 is mounted, with the possibility of moving relative to each other when striking the anvil b on the carriage 4 with the test product 5, the elastic base 9 mounted on the bottom 1 under the anvil 6, and the anvil 6 is mounted on the additional carriage 8 with the possibility of joint movement with it when falling and moving relative to the additional carriage 8 when the anvil 6 bounces from the elastic base 9.

The stand also contains a mechanism 10 for lifting the carriages 4 and 8 to the initial position with the latch 11 and gaskets 12, which serve to adjust the gap between the anvil 6 and: the carriage 4 with the test article 5.

The stand works as follows.

When the latch 11 is deflected, the carriages 4 and 3 fall freely, moving along the cable guides 3. Anvil 6 hits the elastic base 9, bounces and,

moving relative to the additional carriage 8, moves towards the carriage 4 with the test article 5. When the gap is selected, the carriage 4 collides with the test article 5 with the anvil 6 through the braking device 7, while the additional carriage 8 freely continues free fall. SUMMARY OF THE INVENTION A stand for impact testing of products, comprising a frame, a power frame mounted on it with vertical guides, a carriage mounted in the guides to accommodate the test article on it, and an additional carriage on which the first carriage is mounted, the elastic base, mounted on the bed, is impactable with it an anvil installed through gaskets that serve to adjust the gap between it and the carriage with the test product, on an additional carriage with the possibility of joint movement with it When falling and moving relative to it when impacting with an elastic base, a braking device placed between the anvil and the carriage with the test product, and a mechanism connected to the additional carriage for lifting the carriages to their original position and dumping them, while the carriage for placing the test product is installed on an additional carriage with the possibility of changing them relative to each other when striking with the anvil on the first carriage, characterized in that, in order to expand operational capabilities by increasing the impact pulse imparted to the carriage with the test product, the carriage for receiving the test article is freely supported on the additional carriage.
