The study of static and dynamic stiffness characteristics of starting bar forging mainly involves the analysis and research of the stiffness characteristics of the forging in the static and moving state. Here are some key points in this regard:
- Research on static stiffness characteristics:
- Static stiffness refers to the degree of resistance to deformation when the forgings are stressed. Through static analysis and finite element simulation, stiffness parameters such as elastic coefficient and stiffness matrix of forgings under different forces can be calculated.
The study of static stiffness characteristics often includes the analysis of the stiffness curve of the forging, the relationship between deflection and load, etc., in order to evaluate the stiffness level of the forging.
Tensile test, compression test or bending test can be used to measure the stiffness characteristics of forgings under different loading conditions.
- Research on dynamic stiffness characteristics:
- Dynamic stiffness refers to the stiffness performance of the forging under vibration or motion. It is the damping and springback phenomenon of forgings when they are stimulated by dynamic load or vibration.
- The study of dynamic stiffness characteristics needs to consider factors such as frequency response and vibration mode of forging. The stiffness parameters of forgings under dynamic loading can be obtained by means of modal analysis and finite element dynamic analysis.
- The frequency response and vibration characteristics of forgings can be measured and analyzed by experimental means such as vibration test or modal test.
- Significance and methods of characteristic research:
- Research on static and dynamic stiffness characteristics of starting bar forgings can evaluate the stiffness level and force response of the structure, so as to provide the basis for design and optimization.
- Research methods can be combined with experiments and numerical simulations. Experimental results can be used to verify the accuracy of numerical simulation and obtain the stiffness characteristic data under real working conditions.
- During the design process, parameters such as the shape, size and material of the starter bar forgings can be adjusted using optimization design methods to achieve better stiffness characteristics.
By studying the static and dynamic stiffness characteristics of starting bar forgings, the stiffness performance in static and moving state can be fully understood, and reliable basic data can be provided for design, improvement and optimization, so as to improve the performance and reliability of forgings.
