摘要
以偏心-非圆齿轮行星系栽植机构为研究对象,构建偏心-非圆齿轮栽植机构简图并阐述其结构特点;建立栽植机构运动学模型,并在此基础上建立全自动参数优化软件,根据优化软件所得参数建立机构三维实体模型并做动态仿真试验;对机构做运动特性分析,构建虚拟试验台架,对支座受力进行分析;最后,试制样机并进行试验分析.试验表明:栽植机构的运动轨迹和工作姿态与全自动优化软件模拟轨迹一致,机构设计是可行的.
The eccentric-noncircular gear planetary system transplanting mechanism was investigated. The diagram and the structure characteristics of the eccentric-noncircular gear transplanting mechanism were discussed. The kinematics model of transplanting mechanism was established to obtain automatic parameter optimization software. The design parameters of the mechanism were acquired through the proposed software,and the 3D entity model of the mechanism was established to conduct the dynamic simulation test. The virtual experiment platform was constructed to analyze the support pressure. A prototype was constructed, and the seedling tests were conducted. The experiments show that the kinematics trajectory and the working attitude of the transplanting mechanism are consistent with the trajectory of computer simulation. The proposed mechanism design is reasonable.
