压捆机压缩频率与压缩室三维应力关系的试验研究
Experimental Study on the Relationship between the Compression Frequency and the Three-dimensional Stress of the Compression Chamber
摘要
Abstract
Compression frequency and three-dimensional stress of the compression chamber affects the productivity and structure size of hay baler directly, so it is the main design parameters. The research uses the hay baler as testing equip-ment and Leymus chinenses as testing materials to explore the relationship between compression frequency and the three-dimensional stress in opening compression. After collecting the three stress data that are in three mutually perpendicular directions of the herbage material in hay baler during its working process, we analyze the relationship among them and their variation trend in different compression frequency. The results show that in the same compression frequency, the three-dimensional stress values are exponentially with the time variation; different compression frequency change the value of the three-dimensional stress, but have no significant effects on the variation regulation of the three-dimensional stress. Simply raising the compression frequency will decrease the x-stress, thus affecting the other two stresses.关键词
