Problems solved by technology

However, its experimental device mainly relies on the pendulum, and it is only suitable for the test of strip-shaped samples under low-speed impact loads. It is difficult to study the warhead and the target plate at the same time, and it is impossible to conduct variable-angle impact experiments, which has great limitations.

specific Embodiment approach 1

[0025] Specific implementation mode one: as figure 1 , figure 2 As shown, this embodiment discloses an experimental device for measuring impact force based on a light gas gun, including an incident plate 1, a separation flange 2, a chute top plate 3, at least one lower connecting slider 4, and a target cabin load-bearing frame 5 , chute bottom plate 6, three protective plates 7, at least one slide bar with groove 8, at least one sensor top block 9, at least two impact sensors 10, at least one upper connecting slider 11, target plate fixture one 13 and target plate fixture two 14;

[0026] The incident plate 1 (by a plurality of bolts) is fixed on one side of the target cabin bearing frame 5 (the incident plate 1 can prevent the high residual velocity target projectile from bouncing back to damage the equipment and injure the experimenter), and the chute bottom plate 6 ( Through a plurality of bolts) is fixedly connected with the bottom of the target cabin load frame 5, and ...

specific Embodiment approach 2

[0030] Specific implementation mode two: as figure 1 As shown, this embodiment is a further description of specific embodiment one. The target cabin load-bearing frame 5 is a cuboid frame, and each beam of the cuboid frame is made of square steel; the aspect ratio of the cuboid frame is (determines the range of impact angles measured) as (At this time, the adjustable range of the impact angle is between 30° and 90°). The definition of impact angle: the acute angle or right angle between the impact direction vector of the target bomb and the normal vector of the target plate surface, the impact angle is 90°, which is the positive impact.

specific Embodiment approach 3

[0031] Specific implementation mode three: as figure 1 As shown, this embodiment is a further description of specific embodiment 1. The shape of the separation flange 2 is a two-stage stepped shaft (the function of the separation flange 2 is to ensure the smooth incidence of the target bullet and prevent the bullet holder from entering the target. cabin. The outer diameter of the bullet holder is greater than the diameter of the incident hole 2-1 of the separating flange 2), and the small diameter end of the separating flange 2 is fixedly arranged in the central circular hole of the incident plate 1.

Abstract

The invention discloses an impact force measurement experiment device based on a light-gas gun and an installation method of the impact force measurement experiment device, and belongs to the technical field of experiment equipment. An incident plate and three protection plates are fixed to the four sides of a target cabin heavy frame, a sliding groove bottom plate is fixedly connected with the bottom of the target cabin heavy frame, a separation flange is fixed to a center round hole of the incident plate, and an incident hole is formed in the middle of the separation flange; a sliding groove top plate is fixed to the upper end of the target cabin heavy frame; the lower end of a sliding rod with a groove penetrates through the sliding groove top plate to be arranged in a target bin, and a lower connecting sliding block at the lower end of the sliding rod with the groove is arranged in a second sliding groove of the sliding groove bottom plate; an upper connecting sliding block is arranged in the sliding groove top plate in a sliding mode, the upper connecting sliding block penetrates into the sliding rod with the groove, and the sliding rod with the groove is connected with the upper connecting sliding block; a sensor top block is fixed in the sliding groove top plate, and an impact force sensor is arranged in the sensor top block; an impact force sensor is arranged between the second sliding groove of the sliding groove bottom plate and the lower connecting sliding block; and a first target plate clamp is connected with the sliding rod with the groove, and a target plate is fixed between the first target plate clamp and a second target plate clamp. The impact force measurement experiment device is used for measuring impact force.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and in particular relates to an experimental device for measuring impact force based on a light gas cannon and an installation method thereof Background technique [0002] In experiments and engineering, impact loads often occur. For the measurement of impact force in impact experiments, it is difficult to measure directly due to the interaction between the impacting body and the impacted body. At present, there is a lack of general and simple equipment to complete it. Measurement of impact force after impact contact in impact test. [0003] In 2018, Gong Junjie and others announced a measurement method of instantaneous impact force (patent application number: 201810377692.X), which can realize the measurement of instantaneous impact force. However, the experimental device mainly relies on the pendulum, and is only suitable for the test of long strip samples under low-speed impact...
