【摘要】:精密、超精密加工標(biāo)志著一個(gè)國家制造領(lǐng)域的尖端技術(shù)水平,己成為當(dāng)今世界各國進(jìn)行科技乃至軍備競爭的一個(gè)重要手段,這就要求加工設(shè)備具有極高的精度、動態(tài)穩(wěn)定性和熱穩(wěn)定性。傳統(tǒng)鑄鐵材料越來越不能滿足這些要求。因此,急需尋找一種力學(xué)性能符合要求且熱穩(wěn)定性優(yōu)異的材料。 鑒于樹脂混凝土一般具有較好的力學(xué)性能,優(yōu)秀的熱穩(wěn)定性和優(yōu)異的吸振性,此種材料非常適用于制造超精密機(jī)床床身構(gòu)件。本文對樹脂混凝土材料的組成成分、骨料級配、材料試樣制備、性能測試、顆粒堆積模型、性能的有限元分析等方面進(jìn)行了詳細(xì)論述。 首先,本文對骨料、填料和樹脂粘接劑等成分進(jìn)行了詳細(xì)地分析、對比和選擇。其次,本文對決定樹脂混凝土材料性能的骨料級配問題進(jìn)行了深入研究,,首次將各級內(nèi)骨料顆粒的粒徑分布引入級配理論,并建立了基于Dinger-Funk方程的骨料級配數(shù)學(xué)優(yōu)化模型。通過求解該模型,得到了精度更高的級配結(jié)果。再次,本文根據(jù)所得的級配結(jié)果進(jìn)行了樹脂混凝土試樣的制備,并對其進(jìn)行了性能測試,還總結(jié)了一些制備工藝上的經(jīng)驗(yàn)。最后,本文運(yùn)用Matlab數(shù)學(xué)軟件建立了2D和3D樹脂混凝土骨料顆粒堆積模型,并運(yùn)用Ansys有限元分析軟件對其性能進(jìn)行了模擬和分析。 本文的骨料級配數(shù)學(xué)優(yōu)化模型填補(bǔ)了用于制造機(jī)床構(gòu)件的樹脂混凝土骨料級配的理論空白。樹脂混凝土試樣的制備和性能測試也為后續(xù)研究留下了參考依據(jù)。骨料堆積模型中骨料更加密集,分析結(jié)果也更加精確。
[Abstract]:Precision, ultra-precision machining marks the cutting-edge technology level in the manufacturing field of a country, and has become an important means for countries in the world to compete in science and technology and even armaments. This requires processing equipment to have extremely high precision. Dynamic stability and thermal stability. Traditional cast iron materials can not meet these requirements more and more. Therefore, it is urgent to find a material with excellent mechanical properties and thermal stability. In view of the excellent mechanical properties, excellent thermal stability and excellent vibration absorption of resin concrete, this kind of material is very suitable for the manufacture of ultra-precision machine tool bed members. In this paper, the composition of resin concrete material, aggregate gradation, material sample preparation, performance test, particle accumulation model and finite element analysis of properties are discussed in detail. Firstly, the composition of aggregate, filler and resin adhesive were analyzed, compared and selected in detail. Secondly, the aggregate gradation problem, which determines the properties of resin concrete materials, is deeply studied in this paper. The particle size distribution in different grades is introduced into the gradation theory for the first time, and the mathematical optimization model of aggregate gradation based on Dinger-Funk equation is established. By solving the model, the gradation results with higher precision are obtained. Thirdly, according to the gradation results, the preparation of resin concrete samples was carried out, and the properties of the samples were tested, and some experiences in the preparation process were also summarized. Finally, the 2D and 3D aggregate accumulation models of resin concrete are established by using Matlab software, and its performance is simulated and analyzed by using Ansys finite element analysis software. The mathematical optimization model of aggregate gradation in this paper fills up the theoretical blank of resin concrete aggregate gradation used in manufacturing machine tool components. The preparation and performance test of resin concrete samples also provide a reference for further research. In the aggregate accumulation model, the aggregate is more dense and the analytical results are more accurate.
