| 摘 要： | 在试验研究基础上，对气动振动式精密排种器振盘及种子的运动理论进行分析，证实了排种器处于稳定工作状态下工作参数的正确性，提出了采用仿真分析方法，将气动振盘系统简化成单自由度有阻尼强迫振动，利用试验数据进行振动仿真。仿真结果表明，得到的系统振动刚度及阻尼等参数可基本反应振动系统的正常工作状态，为气动振动式精密排种器设计提供了相应的工作参数和参考。

| Abstract: | Basing on experimental research the movement of the pneumatic precision seed-metering device vibrating plate and seeds in theory were analyzed , The correctness of operating parameters in a steady work state was confirmed by using simulation analysis, The pneumatic vibration disk system simplifying single degree of freedom damped forced vibration, to simulate vibration of experimental data was proposed. Simulation results show that the parameters such as system stiffness and damping vibration can be reacted the normal working state. It provides the corresponding operating parameters and theoretical basis for pneumatic vibration-type precise metering device design. |
