【摘要】：高危場所消防、高層建筑消防以及森林消防做為一個世界性的難題已經(jīng)越來越被重視,由于這些場所發(fā)生火災(zāi)后的不確定性,給滅火工作帶來了極大的困難。滅火彈做為一種新型的滅火設(shè)備,能夠?qū)崿F(xiàn)遠(yuǎn)距離滅火,可以有效地應(yīng)對這些場所的火災(zāi)。目前,世界各國都在該領(lǐng)域進(jìn)行了探索與研究并研制出了一系列相關(guān)的滅火產(chǎn)品。本課題的目標(biāo)是以某動員中心的一些滅火彈產(chǎn)品為基礎(chǔ)研制一種新型的智能滅火彈,該滅火彈由發(fā)射裝置發(fā)射后,能夠自主探測火場的信息,達(dá)到起爆要求后,智能起爆滅火彈使其在火場上空爆炸拋灑滅火劑。本文介紹了國內(nèi)外滅火設(shè)備的發(fā)展現(xiàn)狀。通過對所針對的火災(zāi)場所的分析,以動員中心的幾款滅火彈產(chǎn)品為基礎(chǔ),提出了一種新型的以智能控制引信為核心的滅火彈總體設(shè)計方案,并重點介紹了滅火彈的核心部分的設(shè)計——智能引信控制系統(tǒng)的設(shè)計。完成了滅火彈的總體設(shè)計后,又對滅火彈的各個方面進(jìn)行了分析與研究,驗證滅火彈是否能夠滿足要求。具體分析有以下幾個點:(1)利用ANSYS對滅火彈的尾翼進(jìn)行了分析與校核,通過SolidWorks建立了滅火彈尾翼的模型然后利用有限元分析軟件ANSYS對滅火彈的尾翼進(jìn)行了有限元分析。(2)對滅火彈的內(nèi)外彈道進(jìn)行了分析。內(nèi)外彈道關(guān)系著滅火彈從開始擊發(fā)到飛向著火點這個過程的飛行穩(wěn)定性,因此需要對滅火彈的內(nèi)外彈道建立數(shù)學(xué)模型然后利用MATLAB軟件對滅火彈的內(nèi)外彈道進(jìn)行仿真,并得到了滅外彈內(nèi)外彈道的參數(shù)。(3)對滅火彈的爆炸拋灑與滅火效能進(jìn)行了研究,利用ANSYS/LS-DYNA、AUTODYN軟件對滅火彈的爆炸拋撒過程進(jìn)行仿真,建立了滅火彈爆炸拋撒的數(shù)學(xué)模型,提出了評估滅火效能的方法。
[Abstract]:As a worldwide problem, fire protection in high risk places, high-rise buildings and forest buildings has been paid more and more attention. Because of the uncertainty after fire in these places, it has brought great difficulties to the fire extinguishing work. As a new type of fire extinguishing equipment, the projectile can be used to extinguish the fire in long distance and effectively deal with the fire in these places. At present, countries all over the world have explored and researched in this field and developed a series of related extinguishing products. The goal of this project is to develop a new type of intelligent fire extinguishing projectile based on some fire-extinguishing projectile products of a mobilization center. After being fired by the launcher, the projectile can independently detect the information of the fire site and meet the requirements of the detonation. The intelligent fire-extinguishing bomb causes it to explode and sprinkle with fire extinguishing agent over the fire site. This paper introduces the development of fire extinguishing equipment at home and abroad. Based on the analysis of the fire site, and based on several firefighting projectile products of the mobilization center, a new type of overall design scheme of fire-extinguishing projectile with intelligent control fuze as the core is put forward. The design of intelligent fuze control system is introduced in detail. After the overall design of the fire-extinguishing bomb is completed, the various aspects of the fire-extinguishing bomb are analyzed and studied to verify whether the fire-extinguishing bomb can meet the requirements. Specific analysis has the following several points: 1) using ANSYS to analyze and check the tail wing of the fire-extinguishing bomb, The model of the tail wing of the fire extinguishing bomb is established by SolidWorks. Then the interior and exterior trajectory of the fire extinguishing bomb is analyzed by using the finite element analysis software ANSYS. The internal and external trajectory is related to the flight stability of the fire extinguishing projectile from the beginning to the point of fire, so it is necessary to establish a mathematical model of the fire extinguishing projectile's interior and exterior trajectory and then use MATLAB software to simulate the fire extinguishing bomb's interior and exterior trajectory. The parameters of the exterior and exterior ballistic trajectory of the projectile are obtained. The explosion sprinkling and the fire extinguishing efficiency of the projectile are studied. The mathematical model of the explosion throwing is established by using ANSYS / LS-DYNANAA AUTODYN software to simulate the process of the explosion sprinkling of the fire-extinguishing bomb, and the mathematical model of the explosion and throwing of the projectile is set up by using ANSYS / LS-DYNAAUTODYN. A method for evaluating fire extinguishing efficiency is presented.
