某甘蔗机刀盘横向摆动问题研究
Study on the Lateral Swing of a Sugarcane Cutter
摘要
Abstract
In order to understand the vibration of a sugarcane cutter,taking a prototype as the test object,the two major factors that cause the vibration of the cutter are tested. According to the experimental study shows that the engine excita-tion and road excitation of the cutter does a great contribution. Concurrent now the engine speed is 1100rpm regardless of when constant speed or idling cutter horizontal swing very serious,through the analysis of the test data, it is concluded that this peak may not be caused by the single factor of the engine, which may be related to the cutter itself. The cutter made a modal test,results from the modal test analysis can know that there is a transverse oscillation mode in the excita-tion frequencies of the engine. To solve the problem of cutter cutter transverse swing,so the structure of cutter are im-proved,to test the cutter of reinforced bar,we can know that there is no transverse oscillation in the excitation frequencies of the engine from the analysis results. The optimization scheme solved the problem of the vibration of the sugarcane cutter and it has guiding significance to the improvement of the cutting system in the later period.关键词
