【摘要】：井下機(jī)械式動篩排矸機(jī)能夠促進(jìn)煤炭行業(yè)的綠色開采，有效的解決了煤矸石堆積的危害性問題。更因其工藝系統(tǒng)和裝備結(jié)構(gòu)簡單，易于操作，井下機(jī)械式動篩排矸機(jī)必將成為未來煤炭行業(yè)綠色發(fā)展必不可少的機(jī)械設(shè)備。本文對井下機(jī)械式動篩排矸機(jī)的總體設(shè)計和跳汰分層原理進(jìn)行了方案設(shè)計，對其傳動機(jī)構(gòu)進(jìn)行了運(yùn)動學(xué)分析，，對井下機(jī)械式動篩排矸機(jī)瞬態(tài)動力學(xué)響應(yīng)進(jìn)行了分析計算，最后得出其瞬態(tài)動力學(xué)響應(yīng)的結(jié)果。 井下機(jī)械式動篩排矸機(jī)傳動機(jī)構(gòu)的運(yùn)動規(guī)律對動篩體的運(yùn)動特性影響很大，進(jìn)而影響煤和矸石的篩分效率。本文對傳動機(jī)構(gòu)建立了數(shù)學(xué)模型，根據(jù)封閉的矢量多邊形方程，得出各個桿件的角位移、角速度以及角加速度的方程。然后借助ANSYS Workbench中的Rigid Dynamics剛體運(yùn)動學(xué)分析模塊，對井下機(jī)械式動篩排矸機(jī)的傳動機(jī)構(gòu)進(jìn)行運(yùn)動學(xué)分析及仿真，并以此來驗(yàn)證各桿件的角位移、角速度以及角加速度的方程的正確性，為產(chǎn)品的設(shè)計和應(yīng)用提供完整可靠的理論依據(jù)。 最后本文對井下機(jī)械式動篩排矸機(jī)瞬態(tài)動力學(xué)響應(yīng)進(jìn)行了分析計算，得出其瞬態(tài)動力學(xué)響應(yīng)的結(jié)果，從而獲得了傳動機(jī)構(gòu)的應(yīng)力變化和位移變化規(guī)律。直觀而且精確的展示出井下機(jī)械式動篩排矸機(jī)瞬態(tài)動力學(xué)響應(yīng)的特點(diǎn)，為井下機(jī)械式動篩排矸機(jī)的設(shè)計和應(yīng)用提供充分的數(shù)據(jù)支持。
[Abstract]:The underground mechanical moving screen gangue removal machine can promote the green mining of coal industry and effectively solve the harmful problem of coal gangue accumulation. Because the technology system and equipment structure are simple and easy to operate, the underground mechanical moving screen gangue removal machine will become the necessary mechanical equipment for the green development of coal industry in the future. In this paper, the general design and the jigging layering principle of the underground mechanical moving screen gangue removal machine are designed, the kinematic analysis of its driving mechanism is carried out, and the transient dynamic response of the underground mechanical moving screen gangue removal machine is analyzed and calculated. Finally, the results of transient dynamic response are obtained. The movement law of the driving mechanism of the underground mechanical moving screen expelling gangue machine has a great influence on the moving characteristics of the moving screen body, and then affects the screening efficiency of coal and gangue. In this paper, the mathematical model of transmission mechanism is established. According to the closed vector polygon equation, the equations of angular displacement, angular velocity and angular acceleration of each member are obtained. Then with the help of the rigid body kinematics analysis module of Rigid Dynamics in ANSYS Workbench, the kinematic analysis and simulation of the driving mechanism of the underground mechanical moving screen gangue removal machine are carried out, and the angular displacement of each member is verified by this method. The correctness of angular velocity and angular acceleration equation provides a complete and reliable theoretical basis for product design and application. Finally, this paper analyses and calculates the transient dynamic response of the underground mechanical moving screen gangue removal machine, and obtains the results of the transient dynamic response, thus obtaining the variation of stress and displacement of the driving mechanism. The characteristics of transient dynamic response of the underground mechanical moving screen gangue removal machine are displayed intuitively and accurately, which provides sufficient data support for the design and application of the underground mechanical moving screen gangue removal machine.
