Computer simulation and optimal design method of metal forgings

Metal forgings play an important role in the machinery manufacturing industry, and its design quality and production efficiency directly affect the performance and service life of mechanical products. With the continuous development of science and technology, the application of computer simulation and optimization design method in the design of metal forgings is more and more extensive. This paper will introduce the computer simulation and optimization design method of metal forgings, aiming at providing help for improving the design quality and production efficiency of metal forgings.

The design of metal forgings needs to consider many factors such as mechanics and material science. Before the application of computer simulation and optimization design methods, designers usually need to carry out a lot of experiments and experience accumulation to determine the best design scheme. This method not only consumes time and manpower, but also has low design efficiency, which easily leads to the increase of production costs. Therefore, the application of computer simulation and optimization design method has become an important trend in metal forging design.

Computer simulation technology through the numerical simulation method, the actual production process of various parameters to simulate the calculation, so as to predict the product performance and manufacturability. In the design of metal forgings, the commonly used computer simulation methods include finite element analysis (FEA) and fluid analysis (CFD). Through these methods, designers can quickly obtain the stress, strain, temperature field and flow field of metal forgings under various working conditions, and provide a basis for optimal design.

Optimization design is a modern design method based on computer simulation technology, whose goal is to achieve the best performance of the design scheme under the premise of satisfying various constraints. In the design of metal forgings, the optimization design mainly includes the steps of model establishment, parameter identification and deformation control. Designers need to establish the corresponding mathematical model according to the actual demand, and use the computer simulation technology to solve the model. Through the comparison and analysis of the simulation results, the parameters in the design scheme are constantly adjusted, and the optimal design scheme is finally found.

In order to better explain the application of computer simulation and optimization design method in the design of metal forgings, we choose a specific case to analyze. A company needs to design a new metal forgings, requiring it to have good wear resistance and fatigue resistance in a high-intensity working environment. Firstly, we simulate the stress, strain and temperature field of several different design schemes by finite element analysis method, and compare and analyze their performance. By comparison, we found that a new type of alloy material has better mechanical properties and technological properties.

On this basis, by establishing the mathematical model between the material performance parameters and the forging performance, the processing technology of the new alloy material is optimized by computer simulation technology. By constantly adjusting the process parameters such as heating temperature, deformation and cooling rate, we finally get the best forging process scheme. After the actual production verification, the scheme makes the metal forgings maintain high strength at the same time, has good wear resistance and fatigue resistance, to meet the needs of customers.

Compared with the traditional experience design method, computer simulation and optimization design method have obvious advantages in the design of metal forgings. First of all, the computer simulation technology can quickly obtain the performance parameters under various working conditions, so that the designer can understand the product performance more comprehensively and improve the design efficiency. Secondly, the optimization design method can make the design scheme achieve the best performance and improve the quality and reliability of hardware forgings. Finally, computer simulation and optimization design methods can reduce test and manufacturing costs and improve the market competitiveness of enterprises.

In short, computer simulation and optimization design method have important application value in the design of metal forgings. By combining computer simulation technology with optimization design method, designers can design and optimize metal forgings more efficiently. With the continuous development of science and technology, we have reason to believe that computer simulation and optimization design methods will play an increasingly important role in the design of metal forgings, and contribute to improving the overall level of machinery manufacturing industry.
