Problems solved by technology

However, its experimental fixture structure is relatively complicated, and it is only suitable for testing large target plate samples under low-speed impact loads. It is difficult to study lightweight warheads at the same time. In addition, it needs to be used in conjunction with a specific drop weight testing machine.

specific Embodiment approach 1

[0035] Specific implementation mode one: as Figure 1-Figure 5 As shown, this embodiment discloses a rotating shaft variable-angle loading fixture based on a light gas cannon, including a loading fixture, a protective device, and a hydrogen cannon assembly; the loading fixture includes a height-adjusting connecting plate 1, and two target plate supports 2. Two target plate fastening blocks 3, two adapter shafts 4, two connecting blocks 5, target plate rear clamp 6 and target plate front clamp 7; the protective device includes an incident plate 10, four protective plates 11, The target compartment is connected to the base 12 and the target compartment bearing frame 13; the light gas gun assembly includes a separation flange 14, a bullet holder 16, at least one light gas gun bracket 17 and a light gas gun 18;

[0036]The upper end face of the height-adjusting connecting plate 1 is arranged side by side with two target plate supports 2, and the two target plate supports 2 are det...

specific Embodiment approach 2

[0052] Specific implementation mode two: as figure 1 As shown, this embodiment is a further description of specific embodiment one. The semicircular groove provided on the lower end surface of the target plate fastening block 3 and the semicircular groove provided on the upper end surface of the target plate support 2 The shaped grooves are all knurled grooves; the outer wall surface of the shaft end of the adapter shaft 4 is provided with knurling. It is used to increase the frictional force and prevent the impact force from causing the adapter shaft 4 to rotate.

[0053] The two target plate supports 2 are used to support the target plate 8, the target plate front clamp 7, the target plate rear clamp 6, and the combination of the connecting block 5, and the two target plate supports 2 are arranged symmetrically on the left and right. The semicircular groove at the top is a knurling groove, and the effect of the knurling groove is to increase the frictional force, and is use...

Abstract

The invention discloses a rotating shaft type variable-angle loading clamp based on a light-gas gun and a mounting method thereof, and belongs to the technical field of experimental equipment. Two target plate supports are fixed on a height adjusting connecting plate, target plate fastening blocks are arranged on the target plate supports, semicircular grooves are respectively formed in two opposite surfaces of the target plate fastening blocks and the target plate supports, adapter shafts are arranged in the semicircular grooves, the target plate fastening blocks and the target plate supports are fastened and connected through bolts to press the adapter shafts, and the adapter shafts are fixedly connected with connecting blocks. a connecting block is fixed on the rear side of a target plate rear clamp, and a target plate front clamp and the target plate rear clamp clamp a target plate; a target cabin connecting base is fixed at the bottom of a target cabin heavy frame, an incident plate is fixed on the front side of the target cabin heavy frame, the top and other three sides of the target cabin heavy frame are closed through protective plates, and a loading clamp is fixedly arranged on the target cabin connecting base; the separating flange is arranged in the incidence long hole of the incidence plate in a sliding mode, the separating flange is connected with the incidence plate, and a target projectile sample can pass through a center through hole of the separating flange. The rotating shaft type variable-angle loading clamp is suitable for variable-angle loading of the light-gas gun.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and relates to a loading jig for an impact test and an installation method thereof, in particular to a loading jig suitable for medium- and high-speed impact experiments at different angles of light-weight test pieces and an installation method thereof. Background technique [0002] In experiments and engineering, there are often load cases in which warheads of different materials and shapes with different velocities impact targets with different boundary conditions from different angles, but there is currently a lack of general and simple equipment to complete this experiment. [0003] In 2020, Shuai Hongqi and others announced a fixture for variable-angle impact experiments (patent application number: CN212134324U), which can realize variable-angle impact experiments. However, its experimental fixture structure is relatively complicated, and it is only suitable for testing large ...
