摘　　要：选择了某型号自动装填系统作为研究对象,该系统的核心部件为传输机械臂,传输机械臂的装填时间和控制精度会直接影响整个系统的性能。柔性机械臂的应用使得机器人在运行过程中不可避免的引起弹性振动,对机器人的运动精度造成不良影响,不仅如此,弹性振动还会导致机械臂的结构产生严重的疲劳破坏,缩短机械臂的使用寿命。因此,必须对机械臂的振动进行抑制。基于此,围绕机械设备状态监测及诊断技术仿真开展了深入研究,并提出了基座振动双重柔性机械臂动力学模型,希望由此能够为相关业内人士带来一定启发。This paper chooses a certain type of automatic loading system as the research object.The core component of the system is the transmission manipulator.The loading time and control precision of the transmission manipulator directly affects the performance of the whole system.The application of flexible mechanical arm makes the robot inevitably cause elastic vibration in the running process,which has a negative impact on the movement accuracy of the robot.Moreover,elastic vibration will also cause serious fatigue damage to the structure of the mechanical arm and shorten the service life of the mechanical arm.Therefore,it is necessary to restrain the vibration of the robot arm.Based on this,this paper has carried out in-depth research on the condition monitoring and diagnostic technology simulation of mechanical equipment,and proposed the dynamic model of the double flexible manipulator of pedestal vibration,hoping to bring some inspiration to relevant industry insiders.
