【摘要】：電動(dòng)滾筒作為一種驅(qū)動(dòng)裝置,由于長期受到交變載荷作用需要進(jìn)行結(jié)構(gòu)強(qiáng)度和疲勞強(qiáng)度試驗(yàn)。針對某滾筒廠自行搭建的物理試驗(yàn)臺測試時(shí)間長,消耗資源多,樣機(jī)制造難等缺點(diǎn),在電動(dòng)滾筒設(shè)計(jì)過程中結(jié)合虛擬試驗(yàn)技術(shù),利用虛擬樣機(jī)進(jìn)行虛擬試驗(yàn),以達(dá)到對其結(jié)構(gòu)強(qiáng)度和疲勞強(qiáng)度測試的目的,避免了物理樣機(jī)的生產(chǎn),縮短了設(shè)計(jì)周期,降低了研究成本。搭建電動(dòng)滾筒虛擬試驗(yàn)平臺,為電動(dòng)滾筒的研究指出新的道路。本文針對電動(dòng)滾筒虛擬試驗(yàn)平臺的搭建進(jìn)行研究。首先采用參數(shù)化設(shè)計(jì)方法把電動(dòng)滾筒設(shè)計(jì)過程參數(shù)化、自動(dòng)化。其次對Solid Works軟件進(jìn)行二次開發(fā),使電動(dòng)滾筒虛擬樣機(jī)模型的建立過程自動(dòng)化。最后通過ANSYS Work Bench有限元軟件建立電動(dòng)滾筒虛擬試驗(yàn)環(huán)境,分析其結(jié)構(gòu)強(qiáng)度和疲勞強(qiáng)度。通過開發(fā)電動(dòng)滾筒虛擬試驗(yàn)平臺應(yīng)用程序,實(shí)現(xiàn)電動(dòng)滾筒設(shè)計(jì)、實(shí)體模型建立和有限元分析的一體化。利用電動(dòng)滾筒虛擬試驗(yàn)平臺應(yīng)用程序,分別設(shè)計(jì)和建立壁厚為5mm、4mm和3mm的滾筒體裝配體,并對其進(jìn)行虛擬試驗(yàn)分析,得到滾筒體米塞斯等效應(yīng)力、變形、壽命和安全系數(shù)隨壁厚減小的變化規(guī)律。并總結(jié)了滾筒體應(yīng)力和變形在軸向和周向分布規(guī)律。壁厚減小為3mm的滾筒體通過結(jié)構(gòu)強(qiáng)度和疲勞強(qiáng)度虛擬試驗(yàn),與工廠物理試驗(yàn)結(jié)果一致。電動(dòng)滾筒虛擬試驗(yàn)平臺可減少物理試驗(yàn),節(jié)約企業(yè)成本。
[Abstract]:As a kind of driving device, electric roller needs structural strength and fatigue strength test because of the action of alternating load for a long time. In view of the shortcomings of the physical test bench built by a roller factory, such as long test time, high consumption of resources and difficulty in manufacturing the prototype, virtual test is carried out by using virtual prototype in the design process of electric roller combined with virtual test technology. In order to achieve the purpose of testing the structural strength and fatigue strength, the production of physical prototype is avoided, the design cycle is shortened, and the research cost is reduced. A virtual test platform for electric roller is built to point out a new way for the research of electric roller. In this paper, the construction of electric roller virtual test platform is studied. Firstly, the design process of electric roller is parameterized and automated by parameterized design method. Secondly, the software of solid works is redeveloped to automate the process of establishing the virtual prototype model of electric roller. Finally, the virtual test environment of electric roller is established by ANSYS work Bench finite element software, and its structural strength and fatigue strength are analyzed. By developing the application program of electric roller virtual test platform, the integration of electric drum design, solid model building and finite element analysis is realized. Using the application program of electric drum virtual test platform, the cylinder assembly body with a wall thickness of 5 mm or 4 mm and 3mm is designed and built, and the virtual test analysis is carried out to obtain the equivalent stress and deformation of the cylinder body. The variation of life and safety factor with the decrease of wall thickness. The distribution of stress and deformation in axial and circumferential direction is summarized. When the wall thickness is reduced to 3mm, the virtual test of structural strength and fatigue strength of the roller body is carried out, which is consistent with the results of the factory physical test. The electric roller virtual test platform can reduce the physical test and save the cost of the enterprise.
