Design And Optimization Analysis Of GCP-315 Press

With the development of Chinese manufacturing industry.various kinds of mechanical equipment are more and more widely used.The market puts forward higher requirements for equipment design cycle and quality.Press is the most common equipment for stamping and forming of sheet metal parts.The design of press from simple to complex,which has been updated for many generations.The traditional design method by technician has a large amount of design calculation and a long cycle,which is too dependent on the design experience of designers.For the design of similar models,the reuse rate is not high.Because empirical design is seldom checked and optimized,so the mechanical structure obtained is often too conservative.There are phenomena such as material redundancy and huge mechanical structure.In this paper,the GCP-315 press is designed and developed according to the demands of customer.Aiming at the problems in experience design,the GCP-315 press is studied from three aspects:CAD development,finite element analysis and optimization analysis.First of all,according to the requirements of customer,the overall structure of GCP-315 press is designed,then the main technical parameters of the press are determined,and the key components are designed.By using the secondary development technology of SolidWorks,the method has gone through the steps of dimension calculation,parameter planning,macro command recording,design interactive interface,code writing,etc.Then the three-dimensional parametric design of the main components of GCP-315 press is realized,which greatly shortens the period of design and improves the quality.Secondly,the finite element analysis is applied to the design of GCP-315 press.This method includes the geometric cleaning of the model,defining the material properties,dividing the grid,applying loads and boundary conditions,etc.The static simulation analysis is carried out to obtain the stress and deformation nephogram of main components,and the results are compared with the design allowable value to analyze the static characteristics of components.The structural dynamic characteristics are analyzed by modal analysis with the first six non-zero modal frequencies and modes.Finally,based on the static analysis,the response surface method based on the Kriging proxy model is used to optimize the thickness of the frame and the fillet of the throat.Topology optimization is used to slider,and the optimization process includes selecting the optimization area and non-optimization area,taking the density of the element as the design variable,taking the stress and volume fraction as the constraint conditions,taking the minimum flexibility as the objective function.After 26 iterations,the optimization results are obtained.According to the optimization results,the structure of the slider is modified,and the static analysis of the optimized model is carried out again.Then,the mechanical properties of the slider before and after optimization are Compared.After optimization,the weight of the frame is reduced by 7.77%,and the slider is reduced by 14.3%,so the frame and slider are lightened.After verification,the modified structure also meets the allowable requirements of strength and stiffness.The optimized model has a certain reference to the design of the actual structure,and it can also be applied to the lightweight design of other products,shorten the research and development cycle,and improve the competitiveness of enterprises.
