Structural Vibration Modal Analysis

This tool is utilized for structural vibration modal analysis and can be employed to analyze frequencies and other characteristics of multi-degree-of-freedom structures. During the analysis process, factors such as material properties, geometric shape, and dimensional parameters can be incorporated to derive dynamic response characteristics and modal shapes of the structure. The implementation typically involves eigenvalue decomposition algorithms where mass and stiffness matrices are processed through numerical methods like the QR algorithm or Lanczos iteration. Additionally, the tool can analyze damping characteristics and degree-of-freedom parameters, providing detailed analytical results and conclusions through frequency response function calculations. Key functions include modal parameter identification and frequency domain analysis, which help visualize mode shapes through displacement vector outputs. Therefore, in structural design and optimization, employing this tool enables comprehensive understanding of vibration characteristics and response behavior, thereby enhancing structural safety and reliability through parameter sensitivity analysis.
