Development of Software System of Crawler Crane Platform Fatigue Life Reliability Analysis

摘要

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.
