摘　　要：采煤机截割部行星机构工作环境恶劣,受到的冲击载荷较大且内部润滑情况复杂。为了更加准确地计算行星机构动态特性,提出了一种基于Abaqus的光滑粒子流体动力学(Smoothed particle hydrodynamics,SPH)方法。以MG400/951WD型采煤机为工程对象,通过三维建模软件Pro/E建立采煤机整机三维装配模型,导入Adams中进行多体动力学仿真,并输出载荷文件。在Abaqus中建立行星机构流-固耦合模型,运用显式动力学求解器进行非线性齿轮啮合动态分析,验证了油液无网格化特征对比传统动力学分析法具有天然优势,可广泛应用于工矿设备关键结构件的动力学研究中。The planetary mechanism of shearer cutting department operates in harsh environment,suffers heavy impact load and complicated internal lubrication.In order to calculate the dynamic characteristics of planetary mechanism more accurately,a Smoothed Particle Hydrodynamics(SPH)method based on Abaqus is put forward.Taking MG400/951WD shearer as the engineering object,the three-dimensional assembly model of shearer is established by three-dimensional modeling software Pro/E,which is imported into Adams for multibody dynamics simulation and output load file.The fluid-solid coupling model of planetary mechanism is established in Abaqus,and the dynamic analysis of non-linear gear meshing is carried out by using explicit dynamics solver,which verifies that the oil meshless feature has natural advantages over traditional dynamic analysis method and can be widely used in the dynamic study of key structural parts of industrial and mining equipment.
