Lateral Vibration Analysis
INERTANCE has performed the lateral vibration analysis (rotor dynamics analysis) with necessary design tools for turbo-machinery that includes centrifugal and axial compressors, centrifugal pumps, steam & gas turbines, motors, and gear applications. The rotor components including blades, impellers, etc have been modeled based on manufactured drawings, which can generate a mass-elastic lateral model of rotor assembly.
INERTANCE has a capability to perform below kinds of rotor dynamics analysis.
- Lateral vibration analysis
- Rotor dynamics analysis
- Damped eigenvalue (Critical speed) analysis
- Undamped critical speed map
- Train lateral vibration analysis
- Mode shape
- Campbell diagram analysis
- Bearing stiffness and damping coefficients
- Separation margins as per API requirements
- Forced response analysis (Unbalance response analysis)
- Bearing clearance assessment
- Stability analysis
- Log decrement
- Oil whirl and whip against rotor instabilities
- Transient analysis
- Forward and backward mode
- As per API 610, 611, 612, 617, 672, 684, etc. (Any other API Standard)
In addition, the linearized coefficients are calculated for various bearing types with application of any seal type step by step. INERTANCE can provide various kinds of rotor dynamics analysis as requested in API standards as below.
