Operational Deflection Shape (ODS) and Modal Analysis are critical for diagnosing complex dynamic issues in machinery. ODS analysis visualizes structural deformation at a specific frequency, allowing for a comprehensive understanding of the effects of forces such as unbalance, misalignment, and resonance on the entire structure. Modal analysis, on the other hand, focuses on identifying natural frequencies and resonance conditions using acceleration data. These methods are essential for:

• Pinpointing root causes of complex vibration issues
• Understanding the frequency response of the structure or equipment
• Optimizing the equipment’s design and operational performance

Modal analysis allows us to determine structural parameters like natural frequencies, damping ratios, and stiffness, providing insights into how to mitigate resonance and vibration-related failures.
