玉米秸秆饲草化试验台的设计与分析

Design and analysis of test bench for maize straw pulverization

在玉米秸秆饲草化过程中,由于饲草化机械的刀片齿的形状和间距、摘穗辊和破茎辊的转速、两辊中心距、摘穗辊与破茎辊的传动比等,均是影响玉米秸秆饲草化效果的重要因素,因此设计出方便改变各参数的实验台,对机器的优化具有重要意义,同时对实验台机架进行模态分析,避免在实验过程中由于选择因素水平不当,导致机器的损坏和安全隐患。

In the process of maize straw pulverization,many factors have impacts on the degree of maize straw pulverization including shape and distance of blades,center distance and speed of snapping rollers and straw smashing rollers,and transmission ratio between them,etc.Therefore test bench was designed which was convenient to adjust various parameters and it is very significant for optimization of the machine.In order to avoid damage of machine and potential security risks due to disadvantages of factors selected,it is very meaningful to carry out modal analysis of the framework.
