Abstract
Description
Technical Field
[0001] The present invention relates to the field of explosion-proof equipment detection, in particular to a simulation arm test bench mechanism for riot shield performance testing. Background Art
[0002] Riot shields are a common defensive device used by modern riot police. Their specific structure consists of a shield plate and a support plate. The shield plate is often convexly arc-shaped or rectangular, with the support plate attached to the back of the shield via connectors and fixed. The support plate is equipped with a single handle, dual handles, or a buckle and handle.
[0003] The riot shields used by riot police are generally used to deal with low-level conflicts such as group riots, and can effectively block blows and thrusts from objects such as bricks, stones, sticks, and glass bottles. The riot shields used by special police generally also have the functions of bulletproof, shock wave proof, and strong light proof. Although the explosion-proof shield looks transparent and fragile, it is actually very strong and tough and not easy to break. It can withstand the squeeze of small vehicles and can withstand stabs when facing knife-wielding personnel. It can withstand close-range shooting from light weapons and is also effective against shock waves and shrapnel from grenade explosions at close range. When advancing, the first member of the team often holds a riot shield to provide cover for the members behind him.
[0004] The existing performance test of riot shields is mainly carried out in accordance with the test methods for the puncture resistance, impact resistance and impact resistance of the riot shield body in the standard GA 422-2019 "Police Riot Shields". Among them, when testing the impact resistance, a certain speed and energy are applied to the shield, and then the shield is judged to be qualified by measuring the depth of the dent to be less than 30mm. Such a test scheme has many defects. For example, the riot shield is small in size, and it is in a "V" shape after being hit. The dent depth is much greater than 30mm. It is obviously not enough to use this method to judge. In addition, this test method is mainly used to detect whether the equipment is qualified, but it knows nothing about the degree of damage to the human upper arm structure under heavy blows. There is a lack of test parameters for evaluating human injuries, and it is impossible to effectively and comprehensively test the protective performance of the riot shield.
[0005] Therefore, it can be seen that how to accurately test the impact resistance and impact resistance of riot shields while effectively testing the impact protection ability of riot shields on the user's arms (that is, the degree of damage to the user's arms when the user uses the riot shield for protection) is an urgent problem to be solved in this field.

[0019] (3) Beneficial effects
[0020] The present invention provides a simulation arm test bench mechanism for testing the performance of riot shields, which has the following features:
[0021] Beneficial effects:
[0022] 1. This invention uses a highly biomimetic simulated arm mounted on a rotatable main support plate to conduct explosion-proof tests on explosion-proof shields. Four different types of sensors installed inside the arm assembly and on the test bench can accurately measure and collect the impact load values transmitted from the test shield to the human arm, ensuring comprehensive coverage of key stress areas. The different types of sensors complement each other and provide comprehensive perception of external contact and internal forces, thereby improving measurement accuracy.
[0023] 2.

Secondly, by adjusting the degree of compression between the damping ring in the rotating support seat and the major and minor axes of the rotating support seat through screws, the total damping of the main support plate and its upper components can be adjusted to a value of 1 G, which can accurately simulate the actual posture of a human arm holding a shield and ensure the equivalence of the initial test conditions.
[0024] 3. The design of the test base and rotating support ensures that the height of the simulated arm fixed on the support plate meets the parameter requirement of 50% of the male standing elbow height in the Chinese anthropometric parameters.

The carpal bone 502 and upper arm 503 are fixed by the multi-axis force and torque sensor S04 through bolt B08.
[0046] According to the distance between the left and right grips of the tested shield 901, adjust the positions of the left arm support frame 401 and the right arm support frame 402 on the main support plate 301, and secure and lock them with T-bolts and nuts B05; use the support frame elastic pressing buckle 601 to fix the simulated arm assembly 5 to the left arm support frame 401 at the position of the wrist bone 501 of the simulated arm assembly 5 and fix it with bolts B04; use the support frame elastic pressing buckle 602 to fix the simulated arm assembly 5 to the right arm support frame 402 at the position of the upper arm 503 near the elbow 504 of the simulated arm assembly 5 and fix it with bolts B04;

The dynamic torque sensor S02 is fixed to the main support plate 301 with bolts B06. The measuring axes on both sides of the dynamic torque sensor S02 are respectively connected and fixed to the flanges of the long axis 701 and the short axis 702 of the rotating support seat with bolts B03;
[0049] Use the bolts B01 on the left and right rotation support bases 201 to adjust the degree of compression of the damping ring 801 inside the rotation support base and the rotation support base long axis 701 and rotation support base short axis 702, so that the main support plate 301 is perpendicular to the test bench base 101, and keep the damping of the main support plate 301 and all the components thereon at a value of 1 G.
[0050] During the test, an external impact device was used to strike the shield under test. The multi-axial force and torque sensor S04 connected to the arm carpal bone 501 and the upper arm 503 was used to measure the force and torque values transmitted from the handle on the side of the metacarpal bone 501 to the wrist of the simulated arm 5. The three-axial acceleration sensor group S01 on the left arm support frame 401 can measure the acceleration values generated by the impact load on the shield in the three axes. The uniaxial dynamic tension and pressure sensor S03 connected to the elbow 504 of the simulated arm 5 can measure the tension and pressure values generated on the simulated arm due to the deflection of the shield along the left and right handle directions. The dynamic torque under the main support plate The sensors are used to measure the torque value generated by the rotation of the simulated arm assembly 5 along the left and right handle axes. The design of four different types of sensors can ensure that when the shield 901 under test is twisted and flipped at a certain angle, the test bench mechanism can accurately measure the impact load value acting on the simulated arm assembly 5, thereby sensing and collecting the impact loads on the arm assembly 5 at different positions and directions in real time, ensuring full coverage of key stress areas and improving perception accuracy. The measured data can be used to evaluate the degree of damage to the arm structure under impact load and scientifically evaluate the impact protection capability of the riot shield on the user's arm.
