Case study 3

The Challenge

A client’s press has been having a vibration problem for the last 5 years, which has resulted to replacement of encoders twice every year. OCE was called upon to investigate the root cause.

The Methodology

Modal and stress analysis were carried out to identify:

• Design errors
• Excessive vibrations overstressing the encoders
• Deformation patterns of the plate structure
• The root cause of the underperformance
• Increased safety risks

The Outcome

After implementing all the corrective actions recommended, there was the following outcomes:

• Re-designed and optimised encoders
• Vibration was brought to an acceptable level
• Increased the encoders reliability
• Increased revenue by 12%
• Decreased safety risks
