Synthetical Reliability Analysis Model of CNC Software System

Platform is one of the most important load-carrying parts of crawler cranes, one software system of crawler crane platform fatigue life reliability analysis is developed in the paper. It is based on the finite element analysis model by applying parametric design language APDL Using ANSYS Transient analysis, the rain-flow counting method has been adopted to deal with stress spectrum by the mean of combining related spare parts material P-S-N curves and adopting Miner linearity fatigue accumulation damage theory. It is developed under Visual Basic6.0 and Access 2007 database, it include five function modules: parametric finite element modeling, finite element analysis, optimization and fatigue life reliability analysis, it has important value to improve the design of crawler cranes.

Hybrid Reliability

This paper proposes a probability-interval mixed uncertainty model considering parametric correlations and a corresponding structural reliability analysis method. First of all, we introduce the sample correlation coefficients to express the correlations between different kinds of uncertain variables including probability and interval variables. Then dependent parameters are transformed into independent ones through a matrix transformation. A reliability analysis model is put forward, and an efficient method is built to obtain the reliability index or failure probability interval of the structure. Finally, four numerical examples are provided to verify the validity of the method.
