    • A simplified calculation model for use in predicting life consumption of a component subjected to loads during operation may be generated. Accordingly, a first set of load input data resulting from a first set of load sessions during operation is received. At least one of stresses, strains and temperatures for a critical area of said component is calculated by a numerical calculation model. Life consumption of said component is predicted based on said at least one of the numerically calculated stresses, strains and temperatures. Said simplified calculation model is generated defining a relationship between load input data and predicted life consumption by: assigning a plurality of linear difference equations for said simplified calculation model, and calculating parameters of said plurality of linear difference equations based on said relationship between the first set of load input data and said numerically calculated predicted life consumption.
    • 可以产生用于预测在操作期间承受负载的部件的寿命的简化的计算模型。 因此,接收在操作期间由第一组加载会话产生的第一组负载输入数据。 通过数值计算模型计算所述组分的临界区域的应力,应变和温度中的至少一个。 基于所述至少一个数值计算的应力,应变和温度来预测所述部件的寿命。 生成所述简化计算模型,通过以下方式定义负荷输入数据与预测寿命之间的关系:为所述简化计算模型分配多个线性差分方程,以及基于所述第一组之间的所述关系计算所述多个线性差分方程的参数 的负载输入数据和所述数字计算的预期寿命消耗。
