Drive Shaft

Estimate boundary of design
Evaluates influences of structural vibrations and calculates the Eigenfrequencies of the test bed and its behavior by using finite element analysis, torsional vibration analysis and real-time modeling.

• Illustrates critical speeds of the shaft couplings
• Analyses the vibrational behavior of the test bed installation
• Examines feedback effects of the installation on the dynamic behavior
• Calculates component loads
• Behavior of shafts and gear boxes in the required frequency range
• Calculation of torsion Eigenfrequencies and resultant torques in the steady state
• Determination of operating speeds and expected loads on individual components
• Vibrational behavior of the ignition process during engine startup
• Influence of cylinder shutdowns
• Gear changes
