摘要:
为得到理想的三平移一转动四维并联振动筛主机构构型,首先运用EDEM软件,分析得到三平移一转动筛面理想的运动输出:沿筛面长度、宽度和高度方向的移动幅值分别为15,15,6 mm,绕筛面法线方向的转动幅值为6°; 然后选择具有3种不同支链布置方式的并联机构SOC{-RRRRR-} SOC{-RRRR-}2-SOC{-S-S-}作为四维振动筛主机构,并得到该机构在3种不同支链布置方式下的运动输出幅值; 再根据理想的筛面运动输出幅值与振动筛主机构在3种不同支链布置方式下的筛面运动输出幅值,应用层次分析法(Analytic Hierarchy Processs, AHP)优选出理想的四维并联振动筛主机构构型; 接着运用EDEM软件对四维并联振动筛在3种不同支链布置方式下的物料筛分过程进行了仿真试验验证; 最后研制了四维并联振动筛样机,并在样机上进行了筛分试验验证。本研究为四维并联振动筛的设计和应用提供参考依据。
Abstract:
In order to obtain the optimal configuration of the four degree of freedom parallel mechanism, the output motion of three translational and one rotational mechanism is analyzed based on EDEM software, and the ideal motion parameters of the screen surface are obtained: the amplitude of x,y,z are respectively 15, 15, 6 mm, and the amplitude of γ is 6 degrees; There are three branched different layouts of the main mechanism of parallel vibrating screen, which can be expressed as SOC{-RRRRR-} SOC{-RRRR-}2-SOC{-S-S-}, the simulation results of the screen surface which are close to the ideal screen surface form are obtained. Then, according to the ideal output motion of the screen surface and the simulation results of the screen surface with three kinds of arrangement modes, the analytic hierarchy process(AHP)is applied to the optimization selection of 4-DOF parallel vibration sieve. Evaluation and the rank of screening efficiency of three kinds of main mechanism are obtained, and the simulation of parallel vibration screening process is verified, finally the prototype is produced. The research of this paper could provide reference for the design and application of 4-dimensional parallel vibrating screen.
