Title: Finite element parametric modeling and analysis on 2500 t ring-rail cranes
Abstract: In order to resolve the time-consuming problem for modeling and analysis on the 2500tringrail cranes under multiple working conditions,a secondary development is initially conducted using APDL language.Afterwards,the finite element parametric model is established.According to the working condition parameters,the finite element modeling and nonlinear analysis are subsequently obtained in terms of different boom lengths,inclination angles,amplitudes and luffing systems.By employing the array technology,coupling technology and pre-stressing method,the luffing system is consequently simulated using the compressive bar unit for boom anti-retrodisplacement device.Eventually,two typical working conditions of 2500tring-rail cranes are applied as examples to validate the effectiveness of parametric modeling and analysis methods.Therefore,this approach paves a venue for parametric modeling and nonlinear analysis on large-scale boom cranes.
