摘要
以芦苇打捆机为研究对象,针对其满载运输工况下抓斗振动对物料完整性的影响进行了振动系统动力学研究。首先分析了油气减振系统的结构组成及工作原理,然后通过对系统各组成环节的分析,推导了油气减振系统的非线性输出刚度载荷和阻尼载荷,并建立了芦苇打捆机振动系统的动力学数学模型,最后利用MATLAB/Simulink对振动系统进行了动力学性能仿真研究。研究结果表明,油气减振系统在加入后很好地改善了工作装置的行驶平顺性和抓斗内的物料完整性。
Taking reed halvester for the study,aiming at materials integrity problem caused by bucket vibration in full transport condition,dynamics of the vibration system is researched.Firstly,the structure and working principle of hydropneumatic are analyzed,then deriving nonlinear output stiffness and damping force through the analysis of component part of the system.On this basis,dynamics mathematical model of vibration system of reed halvester is established.Finally,dynamic performance of the vibration system,using MATLAB/Simulink toolbox,is simulated.The results show that hydropneumatic damping system greatly improve the ride comfort of working device and the integrity of the material within the bucket.
