甘蔗地路谱对切割质量影响的仿真分析与试验

Simulation analysis and experiment on influence of road spectrum of cane field on cutting quality

摘要: 小型甘蔗收割机在坡地上行走过程中，切割器会受地面等各种因素的影响产生剧烈振动，影响切割质量。该文利用测量加速度的方法，采集田间路谱，并运用虚拟样机的仿真分析验证了路面的不平度会引起刀盘的振动，经试验分析，最后得出当刀盘转速为600和1 000 r/min时切割质量最好。该研究可为样机的开发提供理论依据。

Abstract: When a mini-type sugarcane harvester moves on the sloping field, its’ cutter suffers from violent vibration, which affects the cutting quality. The field roughness was measured by using the field spectrum with the method of measuring acceleration. The influence of the field roughness on vibration of cutter was analyzed and verified by simulation analysis of the virtual prototype. The results showed that the best cutting quality could be obtained when the blade speed was 600 or 1?000?r/min after experimental analysis. The results can provide a reference for the development of prototype.
