With the rapid development of the global logistics industry, ship port machinery plays an increasingly important role in cargo transportation and logistics turnover. As an important part of port machinery, the performance and quality of ship port machinery forgings directly affect the operation efficiency and safety of the whole port. Therefore, the finite element analysis and simulation of ship port mechanical forgings is of great significance for improving its performance and quality and reducing equipment failure. This paper will introduce the finite element analysis and simulation method of ship port mechanical forgings, in order to provide reference for the research in related fields.
Finite element analysis is a widely used method in engineering analysis. It discretizes a continuous problem into a finite number of units by discretizing a complex system. In the analysis of port mechanical forgings, the finite element method can effectively simulate the mechanical behavior of forgings, and provide a reliable basis for optimization design and simulation.
Firstly, 3D scanner is used to obtain the actual geometry of ship port mechanical forgings, and finite element software is used to construct the model. In the process of establishing the model, the actual structure characteristics of the forging should be fully considered, and the model should be properly simplified, while ensuring that the accuracy of the analysis results is not affected.
Secondly, the material properties of the model are set. According to the actual material properties of the forgings, such as elastic modulus, Poisson ratio, density, etc., they are input into the finite element software to simulate the real properties of the materials.
In addition, the constraint conditions of the model should be set according to the actual working conditions. The setting of constraint conditions should consider the actual working environment and working conditions of mechanical forgings in ship ports, such as force conditions, temperature changes, etc., so as to make the simulation results more close to the actual situation.
Finally, the stress, deformation, mode and vibration parameters of port mechanical forgings under various working conditions are obtained by finite element software. Through the analysis of these parameters, we can fully understand the performance of the forging, and provide a basis for optimal design.
Through the finite element analysis of ship port mechanical forgings, we can get the following main results:
Stress and deformation: Finite element analysis can accurately calculate the stress distribution and deformation of forging under various working conditions. By comparing the stress and deformation under different design schemes or different process conditions, the rationality of the design or process can be evaluated, and the basis for the optimization design can be provided.
Modal and vibration: Modal analysis can obtain the natural frequency and mode of the forging, and vibration analysis can simulate its vibration response when it is subjected to external excitation. By optimizing the modal and vibration parameters, the dynamic performance of forgings can be improved and the damage risk caused by resonance can be reduced.
Contact problem: Finite element analysis can also simulate the contact behavior between forgings, including contact pressure, friction, etc. By optimizing the contact performance, the stability and wear resistance of forgings can be improved, and their service life can be extended.
Through the finite element analysis and simulation of ship port mechanical forgings, we can comprehensively evaluate their performance, and then optimize their design and manufacturing process. The practice shows that this method has remarkable effect on improving the performance and quality of mechanical forgings in ship ports and reducing equipment failure.
However, although finite element analysis has achieved remarkable results in the research of mechanical forgings in ship harbours, there are still some challenges and problems that need further research. For example, how to more accurately simulate the nonlinear behavior of materials, how to deal with complex contact problems and so on. Future research should focus on these areas to improve the accuracy and reliability of finite element analysis.
In addition, with the progress of computer technology and numerical calculation methods, the future finite element analysis will consider more factors such as multi-physical field coupling and multi-scale, so as to more accurately simulate the performance of ship port mechanical forgings under actual working conditions. This will help to further improve the design level and manufacturing quality of mechanical forgings in ship ports.
