The invention discloses a parameterized computational analysis system for a lubricating oil film of an oil film bearing and an operating method of the parameterized computational analysis system. The invention belongs to the technical field of designing of the oil film bearing. A foreground human-computer interface comprises a welcoming interface module, an account management module, a parameter input module, a parameter guide module, a working condition selection module, an analysis flow module and a clock and state prompt module. A background computation program comprises a parameter initialization module, an Ansys parametric design language (APDL) command module, a common command language (CCL) command module, a compound file explorer (CFX) finite element computation module, a different-working-condition program module and an analysis file input/output module. The operating method comprises the following steps of: (1) installing an Ansys in a D disk; (2) starting the parameterized computational analysis system and logging in the system; (3) inputting corresponding parameters; (4) generating an APDL file; (5) starting the Ansys in the background, and generating a model; (6) generating a CCL file; (7) activating a CFX, and carrying out CFX pre-processing; (8) importing an analysis file, and directly solving; (9) carrying out CFX post-processing, checking an analysis result, and outputting an analysis report; and (10) logging out of the system.
Description
technical field [0001] The invention belongs to the technical field of oil film bearing design, and in particular relates to a parametric calculation and analysis system and an operation method for lubricating oil films of oil film bearings. Background technique [0002] As the core component of the rolling mill, the oil film bearing plays a decisive role in the normal operation of the rolling mill. The oil film of the oil film bearing plays the role of bearing load, reducing friction and reducing wear. The research on its performance directly affects the bearing capacity of the oil film bearing and the stability of the oil film. Once the oil film becomes unstable, it will soon enter a sudden oil film shock. , will lead to unstable bearing capacity, unbalanced rotation of the rotor, and even damage to the oil film bearing soon. In addition, the oil film force provided by oil film bearings often shows strong nonlinearity. The commonly used solutions include: finite element m...
