Abstract
Description
Technical Field
[0001] This invention relates to the field of engineering evaluation technology, and in particular to a rapid method for evaluating the effective work capacity of typical components under strong impact loads. Background Technology
[0002] The dynamic response and damage evolution of typical components under uniformly distributed impact loads are directly related to the reliability assessment of protective engineering, impact-resistant structures, industrial safety, and critical equipment. Among these, the "effective work capacity" of a component, as a key indicator characterizing the absorption of external load energy and its controlled deformation and energy dissipation under strong impact, can be used to measure the component's safety margin against strong impacts, energy dissipation efficiency, and failure risk. For rectangular cross-section edge-constrained components, whose force paths are clear and widely used in engineering (such as plate / beam components and their equivalent components), rapid assessment and comparison of effective work capacity under uniformly distributed impact loads with different peak values and durations is of great significance for scheme selection, parameter optimization, and rapid engineering decision-making.
[0003] Currently, domestic and international research on assessing the energy dissipation and load-bearing capacity of components under strong impact loads largely relies on nonlinear dynamic finite element analysis, experimental calibration, or computational processes based on complex analytical approximations. These methods typically require detailed model building, selection of constitutive and failure criteria, and time-history integration, resulting in high computational costs, parameter sensitivity, and results significantly influenced by modeling assumptions. When rapid lateral comparisons of different uniformly distributed impact loads (e.g., high-peak short-duration versus low-peak long-duration) are needed during the engineering design phase, or rapid longitudinal comparisons of rectangular cross-section edge-constrained components under the same uniformly distributed impact load, extensive repetitive simulations or experiments are often required, making it difficult to develop a unified, concise, and rapidly implementable effective means of calculating and comparing work capacity. Especially in scenarios involving rapid comparison and prediction of "specified component - multiple loads" and "specified load - multiple components," existing methods still have shortcomings in terms of efficiency, comparability, and engineering usability. Furthermore, with the development of intelligent design and data-driven methods, algorithms such as reinforcement learning in protective structure design usually rely on an iterative closed loop of "simulation-feedback-update". However, traditional simulation is time-consuming, which means that reinforcement learning must wait for the simulation results after each step of calculation before it can proceed to the next step. The training efficiency and the efficiency of effective data screening are significantly restricted, making it difficult to meet the engineering requirements for real-time, instantaneous judgment and rapid iteration.
[0004] As mentioned above, existing methods for calculating and comparing the effective work capacity of rectangular cross-section edge-constrained members under strong impact uniformly distributed loads still suffer from problems such as high computational cost, low efficiency, insufficient comparability, and difficulty in supporting real-time evaluation and intelligent rapid iteration. Therefore, researching a method that can be used to quickly compare the effective work capacity of the same member under different strong impact uniformly distributed loads, and to quickly compare and predict the effective work capacity of different members under the same strong impact uniformly distributed load, is of great significance for improving engineering evaluation efficiency and supporting rapid design and decision-making of protective structures. Summary of the Invention
[0005] The purpose of this invention is to provide a rapid evaluation method for the effective work capacity of typical components under strong impact loads. This method can obtain comparable and consistent evaluation results without repeating high-cost simulations or experiments, which can significantly improve the efficiency of engineering scheme selection, parameter optimization and rapid decision-making. It can also provide rapid evaluation support for simulation feedback iteration and data screening in intelligent design.
