Magnesium forgings in construction machinery are key components to withstand heavy loads, and their performance and reliability are crucial to improve the efficiency and safety of construction machinery. In order to realize the optimal design of magnesium forgings, it is necessary to carry out calculation simulation and structure optimization. This paper introduces the calculation simulation method and optimal design strategy of magnesium forgings of construction machinery.
Firstly, according to the mechanical property parameters of magnesium forgings, the elastic modulus, yield strength and tensile strength of the materials can be obtained by experimental testing. These parameters are the basis of computational simulation. Next, the finite element simulation method can be used to analyze the magnesium forgings. The geometric model of magnesium forgings is divided into finite elements, and the physical fields such as stress and deformation are simulated and analyzed by finite element theory and numerical calculation method. This can evaluate the stress of magnesium forgings under different working conditions and provide basic data for optimal design.
Secondly, the optimization design of magnesium forgings can be considered from three aspects: the selection of materials, the topology optimization of structure and the optimization of process parameters. In terms of material selection, it is necessary to comprehensively consider the strength, toughness and corrosion resistance of magnesium forgings, and evaluate the actual working conditions and cost factors to select the appropriate material. In terms of structure topology optimization, the lightweight and performance optimization of magnesium forgings can be achieved by adjusting the material layout and shape design. The geometric shape of magnesium forgings can be optimized by topological optimization method to improve its mechanical performance and stiffness. In terms of the optimization of process parameters, the forming quality and mechanical properties of magnesium forgings can be improved by optimizing process parameters such as hammering frequency, hammering force and temperature in view of the stress field distribution and texture evolution during the forming process.
Finally, the effectiveness of computational simulation and optimization design can be verified by example analysis. Select a specific magnesium forgings in construction machinery for case analysis, introduce the calculation simulation and optimization design method for the magnesium forgings, and give the corresponding simulation results compared with the actual test data to verify the accuracy and feasibility of the design scheme.
In summary, the performance and reliability of magnesium forgings of construction machinery can be improved through calculation simulation and optimization design. This will help meet the high strength and lightweight requirements of construction machinery under heavy and complex working conditions. In the future research, the calculation simulation method and optimization design strategy can be further improved to improve the design level and application effect of magnesium forgings of construction machinery.
