摘要： Methods, systems and computer program products for assessing residual life of an airfoil, which would experience high cycle fatigue failure under at- or near-resonance vibration condition, are provided. The method includes receiving, at a processing system, at least one vibration response parameter associated with the airfoil. The method processes at least one cracked airfoil finite element model. Processing the cracked airfoil finite element model includes accessing the cracked airfoil finite element model, computing a modal stress intensity factor (SIF) of the cracked airfoil finite element model using fracture mechanics based finite element analysis, and computing a vibratory SIF based, at least in part, on the modal SIF and the at least one vibration response parameter. The method then computes a residual life indicator of the airfoil based, at least in part, on the vibratory SIF.

The membership functions are defined at least in part by a washer operating state that is to be sensed during initial washer operation, and the method includes obtaining a value for the clothes load weight, sensing a value of the washer operating state, and determining a degree of fulfillment of the sensed value in each of the membership functions defined for that given clothes load. The degree of fulfillment represents the relative proportion of the various fabric types for which membership functions are defined, and the information regarding the resultant degrees of fulfillment may be employed in controlling the operation of the washer for optimal performance. The apparatus constitutes a washer controller having a microprocessor that receives signals corresponding to the weight of the clothes load, the sensed value of the predetermined washer operating state, and has stored therein the data necessary to generate the set of membership functions for each clothes load weight.
