Enhanced Virtual Excitation Method

The Enhanced Virtual Excitation Method finds extensive applications across civil engineering, aerospace, and mechanical engineering domains, particularly for random frequency-domain analysis of large-scale structures. The enhanced version employs more precise numerical methods and optimized algorithms to better simulate structural responses under actual working conditions. For instance, in civil engineering, this method can simulate building responses during natural disasters (such as earthquakes and storms) through frequency-domain analysis algorithms that calculate structural transfer functions and random excitation spectra, enabling engineers to improve seismic performance. In aerospace applications, the method models spacecraft dynamic responses during high-speed motion using sophisticated matrix operations and spectral decomposition techniques, facilitating enhanced spacecraft design and performance optimization. For mechanical engineering, the enhanced method simulates mechanical component responses under operational conditions by implementing efficient computational procedures that handle complex boundary conditions and material properties, thereby improving mechanical design and performance. The implementation typically involves coding frequency-response functions, power spectral density matrices, and Monte Carlo simulations or fast Fourier transform algorithms for efficient computation. Thus, the Enhanced Virtual Excitation Method serves as a powerful computational tool that helps engineers better understand and optimize various structural designs and performance characteristics through advanced numerical simulation techniques.
