摘要
运用项目前期试验获得的蔗地路面不平度的功率谱密度(PSD)曲线,并借助多体动力学软件ADAMS中ADAMS/Vibration这个模块,对小型整杆式甘蔗收获机的简化模型进行振动仿真,得到了刀盘的振动特性曲线。通过对比试验与仿真结果分析刀盘的幅频曲线,验证了模型与仿真结果的正确性,对后期耦合激励源对刀盘振动特性的探究有重要意义。
With sugarcane road roughness power spectral density （PSD） curve obtained in pre-project, and combined the multi-body dynamics software ADAMS and it＇ s module ADAMS / Vibration, to analysis the vibration of simplified model for small-scale sugar cane harvester, finally got the amplitude-frequency curve of the cutter vibration. Then through the experiment to verify the con＇ectness of the model and simulation results, all researches above have great significance to the analysis of the coupled excitation source effect for the cutter.
