Industrial Automatic Control Systems and Controllers Annotation << Back Criteria Modeling in Qualifi cation Standards Synthesis A.A. Moiseev Criteria model of friction wear was developed for pump plunger basing on anti-wear fuel properties. It’s intended for friction wear forecasting at defi nite conditions. Optimal parameterization was based on wear criterion invariance. Relation between criterion and its mean value with minimal variation was interpreted as compatibility equation for criterion and its parameters including wear duration. It allows using this equation for wear forecasting at some conditions and for different exploitation periods. To get guaranteed forecast it was proposed to perform model parameterization at extreme wear conditions which were chosen using step-by-step approximation on the base of factor experiment planning. Such model can be used for guaranteed forecasting and hence for qualifi cation standards getting.
