摘要
为了确保桁架机器人在设计阶段满足模态性能要求,在设计前期需要对桁架机器人进行模态分析研究。本文首先根据物流工厂中的实际需求,确定桁架机器人的整体结构,并建立三维模型;然后基于ABAQUS有限元仿真平台提取桁架机器人的前十阶固有频率以及振型;最后通过模态试验方法对桁架机器人的实体缩小模型进行分析。结果表明:模态试验结果中存在四种振型与ABAQUS分析结果中的四种振型吻合程度较高,验证了仿真实验的可靠性。所做分析为避免发生共振及后续改进等研究提供理论支持。
In order to ensure that the truss robot meets the modal performance requirements in the design stage, it is necessary to conduct modal analysis on the truss robot in the early design stage. This paper firstly determines the overall structure of the truss robot and establishes the 3D model according to the actual requirements in the logistics factory. Then the first ten natural frequencies and modes of the truss robot are extracted based on ABAQUS finite element simulation platform.Finally, the model of truss robot is analyze d by modal test. The results show that the four vibration patterns existing in the modal test results are in good agreement with the four vibration patterns in the ABAQUS analysis results, which verifies the reliability of the simulation experiments. The analysis performed provides theoretical support for studies such as resonance avoidance and subsequent improvements.
