摘　　要：针对基于FLUENT软件计算滑动轴承存在需要调整偏位角而多次划分网格,导致计算效率低的问题,提出了一种改进算法,通过采用C++和动网格技术并编写UDF程序,实现了轴承静平衡位置偏位角的自动迭代。采用提出的计算方法对轴承油膜压力分布及静特性参数求解,并与理论数值计算结果进行对比,验证了计算模型的正确性,提高了计算效率。Based on FLUENT software to calculate sliding bearing need to adjust attitude angle and mesh for many times of low efficiency,an improved algorithm was proposed,by using C++and dynamic mesh technique and writing UDF program,the attitude angle of bearing static equilibrium position automatic iteration was realized.Oil film pressure distribution and static characteristic parameters of bearing were solved with the calculation methods,and compared with the results of numerical calculation,the validity of the calculation model was demonstrated and the computational efficiency was improved.
