| The inverted drawbench is an important pipe drawing equipment.As the main supporting component,its structural performance has a great impact on the safety and drawing accuracy of the whole machine.Therefore,it is necessary to analyze and optimize the supporting component.Moreover,as a special structural component of the inverted drawbench,the supporting component has the characteristics of serialization.According to this feature,making parametric analysis and optimization of the supporting component effectively reduces the repetitive work and improves the efficiency of product development.In this paper,the parametric analysis and optimization template programs for the support component of the inverted drawbench have been compiled.And the parametric analysis and optimization system for the supporting component has been built.The specific work is as follows:(1)According to the structural characteristics and ideas of the supporting component,parameterize some structural dimensions as independent driving parameters,and establish the correlative expressions between other dimensions and driving parameters.At last,establish the parameterized model of the supporting component.(2)Based on the finite element method,carry out the parametric static analysis and modal analysis of the supporting component.Write the APDL template programs of parametric static analysis and modal analysis of the support component by ANSYS parametric design language APDL and driving parameters.Taking the supporting component of drum diameter D1=2200mm as an example,apply the template programs to make static and modal analysis under two typical working conditions.(3)According to the actual situation and the design requirements of the supporting component,two optimization design schemes(static stiffness optimization and frequency optimization)are provided.Establish the optimization mathematical model for each scheme,and determine the optimization method.On this basis,compile the optimization template programs for each scheme.The supporting component with drum diameter D1=2200mm is optimized by using frequency optimization template programs,which effectively improves the modal frequency value of the supporting component and avoids structural resonance.(4)Finally,in order to facilitate the operation and management,combining with the above research results,develop a parametric analysis and optimization system for the support component of the inverted drawbench on the platform of Visual Studio 2015 by C# language.The users just need to make some sample operations,the system will make the rapid design,analysis and optimization of the serialized products of supporting component.Equip for the system with MySQL database,which is used to save some important data in the design process. |
