Modal analysis is a classic engineering method for structural dynamic performance study. It extracts inherent structural parameters including natural frequencies, damping ratios and mode shapes, acting as a core tool for dynamic structural design and fault diagnosis.
In the R&D phase, it eliminates resonance risks and optimizes structural design in advance. In automotive industry, it optimizes body and chassis to improve ride comfort and safety. In aerospace, it inspects rotating blades to detect potential resonance damage.

Modal analysis locates structural damage via changes in modal parameters. It is widely used for bridge monitoring and wind turbine blade inspection to eliminate hidden dangers in advance.
As the foundation of other dynamic analysis, it also supports noise control and load identification, becoming an indispensable technology for engineering R&D across various industries.
