| 在离心复合校准装置极限载荷工况下，为确定桁架强度满足离心复合校准应用需求，对桁架结构进行有限元分析和试验验证。利用ANSYS有限元分析软件，设计仿真过程，完成对该种离心转臂式桁架结构，从结构组成、模型建立、网格划分、载荷约束设置等程序描述整个分析过程。通过分析结果云图，确定桁架受力结果符合机械结构要求。经线加速度计校准试验测试对结构分析结果进行验证，结果表明：桁架的结构强度满足使用要求，变形量与实测值接近，结构分析结果与实际应用测试值相符合，分析结果可靠。此桁架分析过程和验证方式可为类似桁架分析提供参考。 |

| In order to ensure that the strength of the truss meets the application requirements of centrifugal composite calibration under the ultimate load condition of the centrifugal composite calibration device, the finite element analysis and verification test process of the truss structure were studied. ANSYS finite element analysis software was used to design the simulation process to complete the centrifugal boom truss structure analysis. The whole analysis process was described from the structure composition, model establishment, grid division, load constraint setting and other programs. By analyzing the result nephogram, it is confirmed that the stress result of truss meets the requirement of mechanical structure. The results of structural analysis are verified by the calibration test of the linear accelerometer. The results show that the structural strength of the truss meets the requirements of use, the deformation is close to the measured value, the structural analysis results are in accordance with the actual application test value, and the analysis results are reliable. The process and verification method of truss analysis can provide reference for similar truss analysis. |
