基于有限元法的基坑开挖钻机结构分析研究
|
摘要
使用ANSYS有限元方法对JT-50轻型组合式基坑开挖钻机的机架和底座在工作过程中的受力情况进行静力分析,包括计算模型的建立、计算载荷的确定、单元确定和网格划分、数据分析等,得出机架和底座的应力云图和位移云图,验证了机架和底座的结构稳定性。
Using ANSYS finite element method(FEM), this paper makesa static analysis of the working process of the JT-50 light combined excavation drill rack and base, including the establishment of calculation model, the determination of computational load, unit identified and meshing, data analysis, etc., so as to draw thestress nephogram and displacement nephogramof the frame and the base, which verifies the structural stability of base and frame.
