Description

Technical Field

[0001] The present invention relates to the field of mechanical testing and analysis, and relates to a physical virtual simulation-based mechanical testing and analysis system for mechanical testing. Background Art

[0002] Mechanical property testing is an important means to evaluate various properties of metal materials and their components under the action of forces, including performance indicators such as elasticity, inelasticity, stress-strain relationship, etc. These performance indicators are crucial for the development of new materials, the improvement of material quality, and the design and use of metal components. Among them, conducting mechanical property tests on industrial components can comprehensively evaluate the mechanical behavior of components under different conditions, thereby providing a scientific basis for the design and use of products, ensuring the reliability and safety of components during manufacturing and use, and improving product quality, which has practical significance.

[0003] Physical virtual simulation can simulate complex stress and deformation conditions, helping engineers better understand the mechanical behavior of materials. It is widely used in mechanical testing experiments of industrial components, greatly improving the efficiency of design and testing, reducing development costs and risks, and providing strong support for the design and optimization of components.

[0004] However, the existing methods for mechanical testing experiments of industrial components through physical virtual simulation have some deficiencies: On the one hand, most of the existing methods evaluate the mechanical properties of industrial components based on their mechanical property performance in a certain state. For example, the mechanical property evaluation is carried out according to the mechanical property performance of industrial components in the unassembled state, without comprehensively considering the mechanical property performance of industrial components in other states. As a result, the detection dimensions are not diverse enough, making the reliability of the mechanical property evaluation results not high.

[0005] On the other hand, most of the existing methods evaluate the mechanical properties of industrial components based on their mechanical property performance under a single type of load. For example, the mechanical property evaluation is carried out according to the mechanical property performance of industrial components under static load, without comprehensively considering the mechanical property performance of industrial components under other types of loads. As a result, the detection dimensions are not diverse enough, making the reliability of the mechanical property evaluation results not high.

[0006] On the third hand, most of the existing methods evaluate the mechanical properties of industrial components based on the stress and strain at a certain position point or a specified position point on the surface of the industrial component, without covering and detecting and analyzing the stress and strain at multiple position points on the surface of the industrial component. As a result, the reliability of the mechanical property evaluation results is not high. Summary of the Invention
