摘要
为准确快速地对起重机钢制车轮踏面与轨道接触应力的分布状况进行有限元分析,运用ANSYS APDL参数化建模,建立常见的起重机车轮与轨道接触分析的数值模型。该模型通过输入必要的车轮几何参数、网格划分参数和载荷参数即可自行完成实体建模、网格划分、载荷施加和求解。实例应用结果证明整合几何参数化和网格划分参数化的建模方法可大大提高起重机轮轨接触分析效率。
To perform the finite element analysis on the distribution of contact stress between crane steel wheel tread and rail contact accurately and quickly,the numerical model for generic crane wheel-rail contact analysis is built by ANSYS APDL parametrization modeling. By inputting necessary wheel geometry parameters,meshing parameters and loading parameters,the solid modeling,mesh dividing,load loading and problem solving can be carried out automatically. The results of an application example show that the modeling method which integrates geometric parameterization with meshing parameterization can greatly improve the wheel-rail contact analysis efficiency.
