【摘要】：通過懸臂帶式輸送機堆料運行,來料車將物料拋向料場實現(xiàn)堆料作業(yè)。它在懸臂式堆料機中屬于相對獨立的一個機構,主要是由結構件構成的,其結構性能直接影響堆取料機的綜合性能,因此,本文對來料車的力學性能進行研究,以便為來料車的結構改進提供依據(jù)。 本文首先介紹了來料車的主要結構,對來料車進行了選型。通過對來料車工作受力情況進行簡化,繪制出力學模型,計算得出了各點受載情況。根據(jù)受載情況,在力學分析軟件ANSYS中,劃分網(wǎng)格并施加載荷,建立了來料車的有限元模型。通過對來料車進行有限元分析,得出應力與變形云圖,直觀地反映了各點應力值與變形量,為產(chǎn)品的改進提供理論依據(jù)。本論文還對來料車鋼結構的穩(wěn)定性進行了計算,通過計算得知其強度符合要求。最后本論文對焊接工藝進行了研究,從生產(chǎn)制造環(huán)節(jié)提供技術方案,保證來料車焊接結構強度。
[Abstract]:Through the stowage operation of cantilever belt conveyor, the incoming truck throws the material to the material yard to realize the stowage operation. It belongs to a relatively independent mechanism in the cantilever stacker, which is mainly composed of structural parts, and its structural properties directly affect the comprehensive performance of the heap-fetching machine. Therefore, the mechanical properties of the incoming truck are studied in this paper. In order to provide the basis for the structure improvement of the incoming vehicle. In this paper, the main structure of the incoming vehicle is introduced, and the type selection of the incoming vehicle is given. The mechanical model is drawn by simplifying the working force of the incoming truck and the loading situation of each point is calculated. According to the loading situation, the finite element model of the incoming vehicle is established in the mechanical analysis software ANSYS, which is divided into meshes and applied loads. Through the finite element analysis of the incoming truck, the stress and deformation cloud diagram is obtained, which directly reflects the stress value and the deformation amount of each point, and provides the theoretical basis for the improvement of the product. In this paper, the stability of the steel structure is calculated, and the strength of the steel structure is found to meet the requirements. In the end, the welding process is studied, and the technical scheme is provided to ensure the welding structure strength.
