ODS Analysis Software

This BK Connect software performs ODS analysis for time, spectral and run-up/down. It determines the vibration pattern of a structure under given operating conditions; how the structure’s dynamic properties respond to the forcing functions acting on it. The vibration pattern can be shown as an animated geometry model of the structure and listed as displacement, velocity and acceleration in a shape table. 

ODS TYPES AVAILABLE

• Time ODS
  The vibration pattern for an analysed frequency range is determined as a function of time: Includes all frequencies in the analysed frequency range giving an overall vibration pattern
• Spectral ODS
  The vibration pattern is determined for specific discrete frequency components (stationary signals) or order components (slightly varying speed)
• Run-up/down ODS
  The vibration pattern is determined for specific frequency or order components, as a function of rotational speed

USE SCENARIOS

• Analysis of rotating machinery and equipment with internally generated forces
• Analysis of machinery running at fixed or slightly varying speeds due to changed operating conditions
• Analysis of the machinery noise and vibration behaviour related to its rotational and fixed parts
• Analysis of transient phenomena such as door slams, explosions, launches and firing, crash and drop impacts
• Analysis of non-linear systems and frequency-variant analysis such as engine run-up/down
• Testing civil engineering structures that are loaded by ambient forces, such as waves on offshore structures, wind load on buildings, and traffic load effects on bridges
