农用切割机执行机构的仿真与分析
Simulation and Analysis on Running Mechanism of Agricultural Cutter
摘要
Abstract
The hinge force curves were obtained through the simulation and analysis of the actuator based on ADAMS. Considering the kinematic clearance, replaced the ideal kinematic pair between the pin hole and the shaft, and added crash contact force,analyzed the influence of clearance gap size on tool head displacement, speed and acceleration. The influence of the component flexibility on the dynamic characteristics of the mechanism was analyzed. Results showed that Kinematic clearance and component flexibility had the obviously oscillatory occurence on cutter head speed and acceleration .The flexible component caused the peak value of the acceleration curve to decrease on the basis of the oscillation, and the impact of the resistance during the cutting process was relieved. Changing the clearance could reduce articulated member impact strength to some extent and improve the cutting machine execution mechanism dynamic response of the target point cutter head.关键词
