基于ADAMS的往复式谷物振动筛设计与试验
Design optimization and experimental evaluation of a reciprocating grain vibrating screen based on ADAMS system
摘要
Abstract
[Obj ective]The study was aimed to improve the screening and cleaning efficiency of thresher and enhance the job quality.[Methods]In this study,a reciprocating vibrating screen was designed.The stress and motion characteris-tics of grains on the screen surface were analyzed.The displacement equation of the sieve was established.The motion characteristics of the vibrating screen were simulated using ADAMS software.[Results]The characteristic values of grain motion on the sieve surface under different conditions were calculated,and the motion characteristic curves of the points on the connecting rod,the rocker,and the screen surface were obtained.The results showed that under the con-dition that the vibration frequency of the vibrating screen was 25.12 rad·s-1 with the installation angle of the screen surface at 2°,and the vibration direction angle was 23°,the screening efficiency could reach up to 89.8% with the con-veying speed at 0.133 m·s-1 .[Conclusion]The developed system can meet the screening and conveying requirement of grains and achieve effective cooperation between screening and airflow cleaning.关键词
