【摘要】：帶式輸送機作為散裝物料輸送的理想設(shè)備,已經(jīng)被廣泛應用在多個領(lǐng)域,對輸送機的動力學分析也顯得尤為重要。在輸送機系統(tǒng)中,數(shù)量最多的構(gòu)件是托輥,托輥質(zhì)量占整機重量的30%以上。本文首先通過對輸送機設(shè)計和建模方法的研究,選擇Recur Dyn軟件作為建模分析軟件,利用Belt工具包創(chuàng)建帶式輸送機虛擬樣機,通過軟件仿真分析輸送機啟動過程的動態(tài)特性,并將仿真值與理論計算值相比較,驗證模型的準確性。然后,本文提出了一種基于Recur Dyn的輸送機參數(shù)化建模方法,以創(chuàng)建參數(shù)化值和參數(shù)化點的方式實現(xiàn)承載段托輥間距的參數(shù)化建模,保證虛擬樣機模型能夠隨參數(shù)化值的變化而自動更新。最后,本文基于參數(shù)化模型,利用Auto Design模塊提出一種輸送機托輥間距優(yōu)化的方法,以承載段托輥間距為設(shè)計變量,選擇輸送帶波動和輸送機功率為優(yōu)化的綜合性能指標,分別以最小的輸送機功率和最小的帶波動為設(shè)計目標進行優(yōu)化,尋求符合設(shè)計要求的承載段托輥間距最佳值。最終,綜合兩次的優(yōu)化結(jié)果進行整理分析,選擇合適的托輥間距,實現(xiàn)最優(yōu)化的輸送機消耗功率、平穩(wěn)的帶波動。在一般輸送機設(shè)計過程中,托輥間距的選取都是依據(jù)經(jīng)驗值。托輥間距越小,越有利于提高輸送機的動態(tài)特性,但同時會增加托輥數(shù)量,增加輸送機安裝費用,降低系統(tǒng)的經(jīng)濟性。因此,合理設(shè)計托輥間距,不僅能夠保證輸送機穩(wěn)定合理運行,而且能降低能耗,提高輸送機的經(jīng)濟性。針對此,本文以輸送機參數(shù)化建模為基礎(chǔ),首次提出一種基于Recur Dyn的輸送機承載段托輥間距優(yōu)化方法。經(jīng)過優(yōu)化仿真分析,得出承載段托輥間距為1.3m時能實現(xiàn)最小的輸送機消耗功率,達到平均最平穩(wěn)的帶波動。本文提出的輸送機托輥間距的優(yōu)化方法,為以后大型輸送機托輥布置提供了一種可靠的設(shè)計依據(jù)。在今后的設(shè)計研究中,可以改變其中的設(shè)計參數(shù)、目標函數(shù)、約束條件,實現(xiàn)其他優(yōu)化目標。
[Abstract]:Belt conveyor, as an ideal equipment for bulk material transportation, has been widely used in many fields, and the dynamic analysis of conveyor is particularly important.In the conveyor system, the largest number of components is the roller, the mass of the roller accounted for more than 30% of the weight of the machine.Firstly, through the research of the design and modeling method of the conveyor, Recur Dyn software is selected as the modeling and analysis software. The virtual prototype of belt conveyor is created by using the Belt toolkit, and the dynamic characteristics of the starting process of the conveyor are analyzed through the software simulation.The accuracy of the model is verified by comparing the simulation value with the theoretical calculation value.Then, a parameterized modeling method of conveyer based on Recur Dyn is proposed in this paper. The parameterized modeling of roller spacing in bearing section is realized by creating parameterized values and parameterized points.Ensure that the virtual prototype model can be automatically updated with the change of parameterized values.Finally, based on the parameterized model and using Auto Design module, this paper presents a method to optimize the roller spacing of conveyors. Taking the distance between rollers in the bearing section as the design variable, the fluctuation of the conveyor belt and the power of the conveyor are selected as the comprehensive performance indexes of the optimization.The minimum power of conveyer and the minimum fluctuation of belt are respectively taken as the design objective to optimize the optimum value of the distance between the rollers of the bearing section in accordance with the design requirements.Finally, the optimization results of two times are synthesized and analyzed, and the proper distance between the rollers is selected to realize the optimal power consumption of the conveyer and the stable fluctuation of the belt.In general conveyor design process, the choice of roller spacing is based on empirical values.The smaller the distance between rollers is, the better the dynamic characteristics of conveyors are, but at the same time the number of rollers will be increased, the installation cost of conveyors will be increased, and the economy of the system will be reduced.Therefore, the reasonable design of roller spacing can not only ensure the stable and reasonable operation of the conveyor, but also reduce energy consumption and improve the economy of the conveyor.In this paper, based on the parametric modeling of conveyors, a new method based on Recur Dyn is proposed to optimize the distance between the rollers in the bearing section of the conveyer for the first time.Through optimization simulation and analysis, it is concluded that the minimum power consumption of conveyer can be achieved when the distance between the rollers of bearing section is 1.3m, and the average and most stable band fluctuation can be achieved.The method of optimizing the distance between the rollers of the conveyer is presented in this paper, which provides a reliable design basis for the arrangement of the rollers of the large conveyors in the future.In the future design research, the design parameters, objective functions, constraints can be changed and other optimization objectives can be realized.
