Advanced on-site diagnostics and modal analysis protocol for a 20.5 MW power generation gearbox.
Understanding the dynamic behavior of high-speed machinery is critical for preventing resonance-related failures. We delivered expert diagnostic services for a Flender-Graffenstaden TX71/4C gearbox, a 20,500 kW unit operating at high input speeds of 6,044 rpm in a power generation facility.
Our specialists focused on a non-invasive, data-driven assessment. By performing a comprehensive vibration analysis and generating a detailed modal analysis protocol, we mapped the gearbox's dynamic characteristics. This sophisticated diagnostic approach allowed us to verify the unit's operational stability and rule out critical resonance issues without requiring any physical service intervention, providing the client with precise data and peace of mind.
