单圆盘甘蔗切割器切割破头率影响因素的试验

利用甘蔗切割综合试验台,对影响甘蔗切割破头率的因素进行了室内试验。采用数理统计方法及优化、仿真技术,建立了相应的数学模型,探讨了田间因素和结构因素对甘蔗破头率的影响机理。在频率、振幅取最小值和软、硬2种土壤条件下,分别对因素进行了优化,结果表明频率、振幅对破头率影响大,因素较优组合为:刀片刃角21°,刀片切割角30.5°,刀盘倾角11.5°,刀片4片。破头率小于11%。

Experimental Study on Influencing Factors of Broken Biennial Root Rate for a Single Base Cutter of Sugarcane Harvester

The experimental investigations for the influencing factors of broken biennial root rate were made by a sugarcane cutter testing rig.A mathematical model was established for describing the effects of the influencing parameters on the broken biennial root rate.The effects of field factors and structure factors on the broken biennial root rate were discussed.The optimization of the broken rate under the condition of the minimum frequency and amplitude,as well as two soil bases,was performed.The results show that the frequency and amplitude have a remarkable influence on the broken biennial root rate.Under the optimal condition,the broken rate is less than 11 percent.
