摘　　要：针对纯吸式真空收集装置收集作业时,其作业断面不平坦而导致其收集深度无法控制的问题,提出在收集装置内加入导流板以改变作业断面平坦度的研究思路。利用流体力学计算软件Fluent中的k-ε湍流模型,对收集装置的空气动力学特征进行了数值仿真,分析了导流板位置尺寸和安装角度对收集装置内部流场的影响,优化了导流板安装尺寸。建立了真空收集装置实验平台,实验结果表明,研制的真空收集装置在进行地面散料收集时,作业断面平整,收集深度可控。Aiming at that the assignments section is not flat and caused the problem of coUection depth that can＇t control, it puts forward the research approach of changing the assignments section flatness by joining a collection of guide plate in the collecting device. Uses the k-ε turbulence model in the CFD soft of Fluent, and numerically simulats the aerodynamic characteristics of the collecting device. Analyzing the different gradient angle of oriented board effect to the collecting device flow field, and optimizes the installation dimensions of the collecting device. Vacuum collecting device experimental platform is established. The experiment result shows, uses the developed vacuum collecting device to collecting the bulk material on the ground, and the assignments is flat and the collection depth can control.
