Research On Parametric Design Of Truck Crane Boom Based On ANSYS

Along with modern engineering construction’s increase, the truck crane already became an important hoisting equipment, shorten the cycle of the structure and properties of the design,it had also become truck crane to play an important part in modern design development. Through the complex process of structural design of large-scale study found that the structure of a complex finite element modeling and analysis, the parameters of the quantity involved, very complicated formula, labor efficiency is very low and easy to go wrong. Therefore, the thesis established truck crane boom structure parametric fem analysis system by the ANSYS parametric design language APDL, realize truck crane of hoist boom of parametric design process, in the optimization of the structure, raise work performance, reduce the cost of the product development has certain theoretical and practical significance.Based on correlated domestic and foreign references, researched on the practical working condition of truck crane, according to crane design standard (GB/T3811-2008), select truck crane performance parameters, crane boom structure size parameters and load parameters for the characteristic parameters; According to the basic theory of Finite Element Method, determined the truck crane boom structure simplified principle and processing method, established the QY20 truck crane boom structure finite element analysis model by ANSYS. On this basis, based on secondary development function of ANSYS, QY20 truck crane boom structure of parameterized modeling, and carried out parametric model finite element analysis is in typical working conditions, obtained the corresponding stress distribution, realizing the truck crane boom of parametric design process. According to the contrast parametric design model and use menu functions the built model of the stress distribution situation and the maximum stress value, found that these two results are consistent, verifies the truck crane boom parametric design effectiveness of the process. Choose corresponding type of truck cranes to carry crane boom of structural stress test testing, won the crane boom structure in the corresponding working conditions of stress test results. Results show that: the parametric design process conform to the actual situation. Finally, combined with the function of VB (Visual Basic 6.0) interface design, program composition with VB, realized the truck crane boom parametric design process of visualization, it has consummated to the truck crane boom parametrization modelling research.This thesis on truck crane boom structure design, parametric design concepts were introduced into the finite element structural analysis, according to adjust crane boom of the characteristic parameters, it realized automatic generating analysis model and finish the relevant analysis process, shrunk the product design cycle, reached crane boom structure parametric design purposes.
