Description

Technical Field

[0001] The invention relates to a dummy for infrasound wave damage testing. Background Art

[0002] Infrasound waves with a frequency of (0.001-20) Hz (Hertz) are called CS waves. CS waves are not easy to attenuate and have a long wavelength. They can bypass certain large obstacles and diffract. At the same time, CS waves have strong penetrating power and can penetrate obstacles such as buildings, shelters, tanks, and ships. The internal organs of the human body and their components (such as the chest cavity, abdominal cavity, etc.) can be regarded as a series of multi-support and multi-center spring models, and their natural vibration frequencies are also within the CS wave frequency range. When the body is in the CS wave sound pressure field, the elastic wall that constitutes the body will enter a vibration state. When the frequency of the internal organs is the same or close to the CS wave frequency, a resonance state of the human internal organs will be formed, resulting in various adverse reactions. In particular, when the natural vibration frequency in the abdominal cavity, chest cavity and cranial cavity of the human body is consistent with the external CS frequency, it will cause primary damage to the human tissues and organs, and may even lead to death.

[0003] The CS wave dummy can simulate the resonance state of the human head, chest, abdomen and key organs to CS waves of different frequencies and sound pressure levels in the CS sound pressure field, and equivalently simulate the biological response characteristics of key internal organs of the human body in the CS sound pressure field. The CS wave dummy can evaluate the impact and degree of damage of CS waves of different frequencies and sound pressure levels on the human body, and can also provide a basis for the design and development of CS wave protection devices or equipment.

[0004] Traditional testing is done by measuring the degree of damage to objects through infrasound, which is impossible for the human body. Based on the principle of human resonance damage, sensors are generally used to receive infrasound frequencies to achieve infrasound damage detection. Due to the particularity of human tissue and the incomplete expression of sensors, it is impossible to determine the blocking effect of protective gear on infrasound through testing, and protective equipment needs to match human tissue, so a test dummy is needed to implement damage testing. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a dummy for infrasound damage testing, aiming to provide a dummy human body, which can amplify and display the impact of infrasound, and at the same time, combined with the characteristics of the dummy body, can detect the response of various parts of the human body to infrasound, and restore the detection scene more realistically than computer simulation, and can be close to the scope of use, so that more effective suggestions can be given for the design and improvement of infrasound protective gear.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a dummy for infrasound damage test, including a human body structure and a simulation structure; the human body structure includes limbs, head, neck and trunk; each structure is distributed according to the natural structure of the human body; the simulation structure includes a chest simulation module, an abdominal simulation module, a lung simulation module, a heart simulation module, a liver simulation module, a brain simulation module, a spine simulation module and a control module; wherein the chest simulation module, the abdominal simulation module, the lung simulation module, the heart simulation module, the liver simulation module and the spine simulation module are all located inside the trunk and distributed according to the natural structure of the human body; Each simulation module adapts to the infrasound through the organ simulation material, and vibrates under the influence of the infrasound; each simulation module is connected to the control module to transmit the response signal to the external display screen, and the control module is internally provided with a response coupling modeling program, a signal attenuation program, an interference compensation program and a system fault-tolerant program; the response coupling modeling program models the response of the infrasound according to different visceral materials, responds to the sound wave simulated organs used for the test, and achieves the detection purpose; the signal attenuation program is used to simulate the signal attenuated after the signal passes through the human body, the test equipment and the viscera, so that the detection environment is close to the real use environment; the interference compensation program is used to detect the interference signal in the environment, and compensate according to the interference signal to simulate the application environment of the infrasound; the system fault-tolerant program is used to delete the signal data with deviation errors to prevent the system from directly reporting errors; The spinal simulation module is also provided with a nervous system simulation module for simulating the reaction and damage of human nerves after receiving infrasound waves; The control module is connected to each simulation module, and is also externally connected to a display screen and a computer, so as to control the data input and output of each simulation module, and transmit the experimental data to the display screen.

[0007] Furthermore, each of the simulation modules includes a simulated organ and a sensor, the sensor is used to sense the vibration response of each simulation module, and the signal data of the vibration response is input into the response coupling modeling program.

[0008] Furthermore, the vibration response is generated according to the vibration response of the simulation material and the infrasound wave. Different organs use different simulation materials, so the vibration response of each organ is also different.

[0009] Furthermore, the response coupling modeling program establishes the resonant response of human internal organs to infrasound through the response relationship of animal internal organs to infrasound, and at the same time realizes infrasound resonance by using internal organs made of simulation materials, and transmits the resonance signal back to the control module through the sensor.

[0010] Furthermore, a nervous system simulation module is also provided in the spinal simulation module, and the nervous system simulation module includes a neural signal simulation output module and a neural signal trigger detection module; the nervous system simulation module includes a neural control chip and a simulated neural peripheral circuit; the neural control chip is located inside the control module, and is used to control the simulated neural peripheral circuit and simultaneously receive the resonance signal of the spinal simulation module; the simulated neural peripheral circuit is used to simulate the resonance signal output by the spinal simulation module into a nervous system signal, and input it into the neural signal trigger detection module; the neural signal trigger detection module amplifies the simulated neural signal through an amplification circuit, and outputs a response signal of the human nervous system to the outside.

[0011] Furthermore, the neural signal trigger detection module is provided with a three-stage amplification circuit to amplify the signal step by step.

[0012] Compared with the prior art, the dummy for infrasound damage testing provided by the present invention simulates the response of human internal organs to infrasound through simulation materials, relies on its resonance signal to detect the damage of infrasound to internal organs, and further realizes the protection detection of equipment against infrasound. It can effectively simulate the condition of the human body in a real infrasound field and improve the detection effect and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
