马铃薯收获机是马铃薯生产过程中一种非常重要的机械,但马铃薯收获机振动筛的运动规律复杂,经常发生伤薯问题.为此,以某型号马铃薯收获机多杆机构的振动筛为研究对象,利用Creo建立了振动筛的参数化模型,并利用ADAMS对振动筛的运动特性进行了分析.通过分析得到振动筛的振幅范围5.5~31.8mm略微超出了最佳范围10~30mm;速度范围105.5~535.2mm/s符合小于600mm/s的最佳要求;加速度范围0.7~18.7 mm/s2,其最小值小于最佳取值范围2.5~20 mm/s2的下界.利用ADAMS可以准确高效地得到振动筛的运动特性,为振动筛的优化设计提供了理论依据.

Potato harvester is a kind of very important machinery in potato production, but the movement of the potato harvester ' s vibration sieve is complex and vibration sieve offer damage potato.This article takes a type of potato harvest-er' s vibration sieve as the research object.The simplified 3D model of the vibration sieve was built by Creo,and analyzed the motion characteristics of vibrating sieve by ADAMS.The analysis results show that the amplitude range which is 5. 5mm~31.8mm is bigger than the optimum range which is 10~30mm;the speed range which is 105.5~535.2mm/s is in accordance with the best standard which is samller than 600mm/s; the acceleration range is 0.7~18.7mm/s2,the smallest acceleration is out of the optimum range which is 2.5~20 mm/s2.ADAMS can be used to accurately obtain the motion characteristics of vibrating screen, and provides the theoretical basis for the acceptance and optimization design of vibrating sieve.
