本文对球磨机动静压滑动轴承的压力分布进行有限元计算方法及结构参数进行了分析研究。结果表明 ,动静压滑动轴承能综合利用静压和动压轴承的优点。并且对磨机动静压主轴承的设计参数通过复合形法进行优化设计 ,编制了在满足等式和不等式约束条件下以单位承载力下的功率损耗最小为目标函数的通用 Visual Basic程序 ,以提供最佳设计数据 ,并对优化前后的数据进行比较、分析。结果表明 ,这是一种有效的方法。 In this paper, the finite element method and the structural parameters of the pressure distribution of the ball mill dynamic and static pressure sliding bearings were analyzed. The results show that hydrostatic sliding bearings can make full use of the advantages of hydrostatic and hydrostatic bearings. The design parameters of dynamic and static pressure main bearing of mill are optimized by complex method. The common Visual Basic program with minimum power loss per unit bearing capacity as the objective function under the constraints of equality and inequality is established to provide The best design data, and compare the data before and after optimization, analysis. The results show that this is an effective method.
