在轧机轴承失效分析的基础上,运用疲劳理论、工程断裂力学以及机械可靠性理论,提出了轧机轴承寿命预测的物理模型和寿命预测公式,并用FORTRAN语言编制了在IBM-PC上通用的运算程序。以武钢1700冷连轧机工作辊轴承为例,计算结果表明,运用新公式预测的结果比用ISO方法、Timken方法计算的结果更接近于实际情况。附图 5幅,表1个,参考文献7篇。 On the basis of rolling mill bearing failure analysis, the physical model and life prediction formula of rolling mill bearing life prediction are put forward based on fatigue theory, engineering fracture mechanics and mechanical reliability theory. The general computing program on IBM-PC is compiled with FORTRAN language . Taking the work roll bearing of the 1700 tandem cold rolling mill of WISCO as an example, the calculation results show that the results predicted by the new formula are closer to the actual conditions than those calculated by the ISO method and the Timken method.
