摘要
在对振动速度变化成正弦曲线的挖掘铲进行运动学分析的基础上提出了振动挖掘铲的理想工作状态。应用动粘摩阻力模型对振动挖掘铲切入和提升阶段进行了动力学分析。在此基础上,以拖拉机液压输出作为动力源设计了一种液压激振式马铃薯收获机挖掘装置。应用SolidWorks和ADAMS软件建立了虚拟样机模型,在ADAMS中进行了虚拟试验。虚拟试验结果验证了设计的正确性,试验表明,设计的液压激振式马铃薯收获机挖掘装置具有振幅和频率调整方便的特点,在4～10 Hz范围内能较好的进行振动掘削,挖掘铲的平均牵引阻力为1.3～1.9 KN。
In this paper, based on the kinematic analysis of the sinusoidal vibration velocity change of mining shovel, we proposed ideal working state of the vibration mining shovel. Using dynamic sticky friction resistance model, we performed the kinetic analysis of the cutting and ascension phases of the vibration mining shovel. On this basis, we designed a hydraulic vibration potato harvester mining device with the tractor hydraulic output as a power source. Solid Works and ADAMS software were used to build a virtual prototype model. Virtual test re- sults in ADAMS verified the correctness of the design, proving the easy adjustment of amplitude and frequency of the device. This device could effectively vibrate and excavate in the 4 - 10 Hz range. The average traction resistance was 1.3 - 1.9KN.
