Visual Modeling Technology for Computer to Modal Numerical Simulation

Computer technology has brought tremendous changes to our lives. The introduction of visualization technology in the computer system can visually display the data analysis results. In this paper, a modal numerical simulation analysis system is built on the basis of visual modeling. The system is developed using visual modeling software UG. By studying the steps of structural modal analysis and the idea of modal decomposition, the system is applied to identify modal parameters in experiments, and the impulse response function of the system is calculated using natural excitation technology. Compared with the theoretical modal value, the results show that the difference between the theoretical value and the calculated value of the impulse response is very small, and the variation curve is highly coincident, which shows that the system in this paper is very effective in modal numerical simulation.
