加工番茄果秧分离全液压振动系统的仿真分析

针对偏心块式加工番茄果秧分离装置存在的加工及装配精度要求较高等问题，为实现加工番茄果秧的有效分离，利用全液压振动系统取代偏心块式激振机构驱动分离滚筒做周期性的变速回转运动，利用AMESim软件的液压系统仿真功能建立了液压振动系统的仿真模型，对模型中各液压元件的参数进行了设置，并仿真分析了系统中液压马达的压力、流量等参数，结果表明：当输入的控制信号频率为1～5Hz时，系统压力为12MPa，与前期研究试验所得的系统压力值吻合较好，可满足设计及工作要求。

The Simulation Analysis of the Processing Tomato Fruit-Plant Separation Hydraulic Vibratory System

As the eccentric tion so as to the eccentric block processing tomato fruit-plant separation device requires high processing and assembly precision, block vibrator was replaced by the hydraulic vibration system to drive the separation roller for variable rotary mo- achieve the effective separation of the processing tomato fruits and plants. Using AME simulation software, the au- thors established a simulation model of the hydraulic vibration system under the software＇s hydraulic system simulation environ- ment, and set the hydraulic components parameters in the system. The simulation of hydraulic pumps and hydraulic motors＇ pressure,flow and other parameters showed that when the control signal input frequency was 1-5 Hz and the system pressure was maintained stationary to 12 MPa,which was in accordance with the theoretical analysis and met the design and job requirements.
