| description | The invention relates to an online calculation method for fatigue life of a rolling mill coupler, and belongs to the field of intelligent maintenance of metallurgical equipment. The frequent fatigue failure of the rolling mill coupler causes huge harm to steel production, while the existing evaluation method cannot realize real-time co-fusion evaluation of online parameters and complex models. Therefore, the solution method provided by the invention comprises the following steps: establishing a rolling process transient dynamic model and performing simulation, then establishing a fatigue damage offline calculation model to obtain the influence of rolling parameters on a fatigue damage value, then establishing a fatigue damage and working condition parameter quick solving numerical value response surface model and performing programmed packaging, and finally obtaining the fatigue damage and working condition parameter quick solving numerical value response surface model. And then rolling parameters monitored o |
