發(fā)布時間：2018-08-06 09:20
【摘要】：本文在現(xiàn)有礦用救生艙的研究基礎(chǔ)上,借鑒礦用救生艙的設(shè)計思路,從耐壓性、自振性、抗震性、抗爆性以及熱防護性等方面對家用救生艙的艙體結(jié)構(gòu)進行設(shè)計,同時對艙門進行整體的結(jié)構(gòu)設(shè)計。通過AWE中各模塊以及ABAQUS對艙體結(jié)構(gòu)進行了動力學(xué)仿真,驗證所設(shè)計的新型艙體和艙門結(jié)構(gòu)的合理性及可靠性。本文主要從以下方面進行了研究:首先,對新型家用救生艙的整體結(jié)構(gòu)進行設(shè)計,依據(jù)礦用救生艙的設(shè)計思路與總結(jié)的相關(guān)經(jīng)驗,考慮家用救生艙所處的居民住宅樓的室內(nèi)環(huán)境因素,提出了一種新型家用救生艙結(jié)構(gòu),即類三角形艙體結(jié)構(gòu);在現(xiàn)有的鎖緊機構(gòu)的基礎(chǔ)上對艙門進行創(chuàng)新性設(shè)計,設(shè)計出一種帶有新型鎖緊機構(gòu)的艙門。其次,對新型家用救生艙的艙體和艙門進行靜力學(xué)分析,將新型艙體結(jié)構(gòu)(即類三角形艙體結(jié)構(gòu))以及拱形艙體結(jié)構(gòu)分別導(dǎo)入到ANSYS Workbench中,施加0.3MPa載荷作用,得到兩種艙體結(jié)構(gòu)的等效應(yīng)力云圖和總變形云圖;由于家用救生艙整體結(jié)構(gòu)必須保證良好的氣密性,因此單獨對所設(shè)計的新型艙門進行計算和校核,通過分析找到變形量最大的位置,通過校核驗證設(shè)計的可靠性。進而,通過Creo中對類三角形艙體的參數(shù)化建模以及在靜力學(xué)仿真的基礎(chǔ)上對類三角形艙體的等效應(yīng)力、總變形以及質(zhì)量進行了多目標(biāo)優(yōu)化設(shè)計。通過設(shè)計變量與目標(biāo)函數(shù)的關(guān)系曲線,確定影響艙體等效應(yīng)力、總變形及質(zhì)量的主要因素是加強筋的長度與寬度及艙體厚度,通過DOE尋優(yōu)方式找出類三角形艙體結(jié)構(gòu)的最優(yōu)解。再次,對類三角形艙體結(jié)構(gòu)進行結(jié)構(gòu)抗震分析,對優(yōu)化后的類三角形艙體施加地震加速度譜載荷,模擬某一地震工況,進行瞬態(tài)動力學(xué)分析。通過總加速度圖、應(yīng)力圖以及總變形圖分析得出艙體結(jié)構(gòu)的加速度、變形及應(yīng)力均不大,表明優(yōu)化后的類三角形艙體結(jié)構(gòu)滿足抗震使用要求。然后,利用AUTODYNA與ABAQUS軟件聯(lián)合仿真對優(yōu)化后的類三角形艙體結(jié)構(gòu)進行抗爆炸分析。將類三角形艙體結(jié)構(gòu)放置于模擬的居民樓內(nèi),利用TNT進行爆炸試驗?zāi)M,得出爆炸期間房間內(nèi)的壓力云圖以及單室內(nèi)各處壓力在各時刻的變化曲線。采用壓力曲線對家用救生艙進行抗爆分析,得到新型艙體結(jié)構(gòu)的應(yīng)力與變形云圖,從而驗證新型家用救生艙滿足抗爆性能。最后,對類三角形艙體結(jié)構(gòu)進行熱防護性能分析,采用室內(nèi)升溫曲線,分別對艙體的外層、隔熱層以及內(nèi)層進行瞬態(tài)熱分析,得到各層的溫度變化曲線與云圖,結(jié)合隔熱層的結(jié)構(gòu)分析,得出新型隔熱結(jié)構(gòu)滿足隔熱效果的需求。本文對新型家用救生艙從耐壓性、自振性、抗震性、抗爆性以及熱防護性等方面進行了分析研究,得出家用救生艙在遇到不同突發(fā)(如地震、火災(zāi)等)狀況時艙體的等效應(yīng)力云圖及總變形云圖等,驗證設(shè)計的新型家用救生艙結(jié)構(gòu)的可靠性,對家用救生艙的設(shè)計及制造提供理論參考和技術(shù)支持,具有較強的科學(xué)理論意義。
[Abstract]:On the basis of the study of the existing mine lifesaving cabin and the design idea of the mine lifesaving cabin, the cabin structure of the household lifesaving cabin is designed from the aspects of pressure resistance, self vibration, anti-seismic, anti explosion and thermal protection. At the same time, the whole structure of the hatch is designed. Through the modules of AWE and the structure of the cabin, the structure of the cabin is carried out by ABAQUS. The dynamics simulation is used to verify the rationality and reliability of the new type of hatch and door structure designed. This paper mainly studies the following aspects: first, the whole structure of the new household lifesaving cabin is designed. According to the design idea and summary experience of the mine lifesaving cabin, the residential building of the household lifesaving cabin is considered. A new type of household lifesaving cabin structure, that is, the structure of a new type of family life lifesaving cabin, is put forward, and a new type of hatch with a new locking mechanism is designed on the basis of the existing locking mechanism. Secondly, the statics analysis is carried out on the hatch and the hatch of the new type of household lifesaving cabin, and the new type of hatch is formed. The equivalent stress cloud and total deformation cloud of two kinds of hatch structures are obtained by introducing 0.3MPa load into the ANSYS Workbench, and the structure of the arched hatch structure is introduced into the structure of the arched hatch. Check to find the largest position of the deformation and verify the reliability of the design by checking. Then, through the parameterized modeling of the triangle class and the static simulation, the equivalent stress, the total deformation and the mass of the triangle class are optimized by the Creo. The design variables and the targets are designed. The relationship curve of the function determines the main factors affecting the equivalent stress of the cabin, the main factor of the total deformation and the mass is the length and width of the reinforcement and the thickness of the cabin, and the optimal solution of the structure of the class triangle is found through the DOE optimization method. The acceleration spectrum of a certain earthquake is simulated by the acceleration spectrum load, and the acceleration of the structure is obtained through the total acceleration diagram, the stress and the total deformation diagram, and the deformation and stress are not large. It shows that the optimized structure of the triangle class cabin satisfies the requirements of the earthquake resistance. Then, the AUTODYNA and the ABAQUS software are used to imitate the model. The anti explosion analysis of the optimized triangle hatch structure is carried out. The structure of the class triangle hatch is placed in the simulated residential building, and the explosion test simulation is carried out by TNT to get the pressure cloud in the room and the change curve of the pressure in the single room at all times during the explosion. The stress and deformation cloud chart of the new type of hatch structure are obtained by blasting analysis, and the new type of household lifesaving cabin can be verified to meet the anti explosion performance. Finally, the thermal protection performance of the structure of the class triangle hatch is analyzed. The temperature curve of the indoor temperature is used for the transient thermal analysis of the outer layer, the insulation layer and the inner layer of the hatch, and the temperature change curves of each layer are obtained. In this paper, the new type of household lifesaving cabin is analyzed from the aspects of pressure resistance, self vibration, earthquake resistance, anti explosion and thermal protection, and the cabin of the household lifesaving capsule in the case of different burst (such as earthquake, fire and so on) is obtained. The effect force cloud map and the total deformation cloud chart verify the reliability of the new type of household lifesaving cabin structure designed and provide theoretical reference and technical support for the design and manufacture of the household life lifesaving cabin, which has strong scientific theoretical significance.
