目的 解决称量传感器标定装置因进给系统在实际工作时频繁受到电机的振动而可能引发检测装置共振的问题。方法 利用三维设计软件PROE建立称量传感器标定装置进给系统三维模型，结合有限元仿真技术对称量传感器标定装置进给系统进行动态特性分析和瞬态分析，并对模态分析结果进行试验验证。结果 当外界激励频率与进给系统第5阶模态(412 Hz)接近时，进给系统的变形、应力值较大。结论 在实际工作环境中应当避免称量传感器标定装置工作在第5阶(412 Hz)模态频率附近。

The work aims to solve the problem that the feeding system of weighing sensor calibration device is subject to vibration of the motor frequently during actual operation, thus possibly causing the resonance of the detection device. The three-dimensional design software PROE was used to establish the three-dimensional model for the feeding system of weighing sensor calibration device. The dynamic characteristic analysis and the transient analysis of the feeding system of weighing sensor calibration device were conducted in combination with the finite element simulation technology, and the modal analysis results were tested and verified. The results showed that, when the external excitation frequency was close to the fifth-order modality (412 Hz) of the feeding system, the deformation and stress of the feeding system were larger. Therefore, in the actual working environment, the operations of weighing sensor calibration device in the vicinity of the fifth-order (412 Hz) modal frequency should be avoided.
