With the rapid development of manufacturing industry, large-scale complex hot die forging process is more and more widely used in aerospace, energy, transportation and other fields. However, the traditional research and development method of hot die forging process often relies on experience and trial and error, which has the disadvantages of long cycle, high cost and high risk. In order to solve these problems, digital simulation technology is gradually applied in the research and development of hot die forging process, which provides an effective means for process design and optimization.
Digital simulation technology is a kind of technology to simulate and predict the actual system by establishing mathematical model and computer simulation. In the research and development of hot die forging process, digital simulation technology can simulate material deformation, temperature field, stress field and other key processes, and predict the results of product shape, performance and quality. Compared with traditional test methods, digital simulation technology has the advantages of low cost, short cycle and good repeatability.
The application of digital simulation technology in the research and development of large-scale complex hot die forging process
Process design: Through digital simulation technology, the material flow, temperature distribution, stress and strain in the process of hot die forging can be simulated in detail to provide accurate data support for process design. This helps to reduce the number of tests, improve design efficiency, and reduce costs.
Process optimization: Based on digital simulation results, hot die forging process parameters can be optimized, such as temperature, pressure, speed, etc. Through multiple rounds of simulation and optimization, a better process scheme can be obtained to improve product quality and production efficiency.
Process validation: Digital simulation technology can verify process solutions before actual production and predict potential problems and risks. This helps to reduce production risks, reduce scrap rates and improve economic efficiency.
Taking the hot die forging process of an aero engine blade as an example, digital simulation technology is used to simulate and optimize the forming process of the blade. By adjusting the process parameters, the defects such as surface cracks and internal pores of the blades were successfully solved, and the quality and performance of the blades were improved. At the same time, the application of digital simulation technology also shortens the research and development cycle, reduces the cost, and brings significant economic benefits to the enterprise.
By analyzing the application of digital simulation technology in the research and development of large-scale complex hot die forging process, this paper shows its advantages in improving product quality and reducing R&D cost and risk. With the development of computer technology and numerical calculation method, digital simulation technology will play an increasingly important role in the research and development of hot die forging process. In the future, we will further expand the application range of digital simulation technology, improve the simulation accuracy and efficiency, and provide strong support for the sustainable development and innovation of the hot die forging industry.
