Case study
Polyurethane damped torsion damper with double damping effect
To manage the vibrations and forces that occur during operation in a specific application, an innovative torsional damper is used that dampens both torque and vertical forces. The damper is made of durable polyurethane, which thanks to its durability and flexibility gives the product a long service life even in harsh conditions.
Challenge
The current application requires high performance and low frequency of maintenance, which made component wear caused by torsional vibrations and vertical loads a challenge. It was necessary to develop a solution that could effectively mitigate both of these forces to improve durability and reduce the need for repairs.
Solution
Initially, simulations of the damper's ability to handle both torque and vertical forces were carried out to ensure that the correct level of damping would be achieved. Based on these results, a series of test casts were made in different hardnesses of polyurethane to optimise the damper's performance. The test casting was followed by extensive testing to ensure that the torsional damper met the requirements of the application.
Outcome
The test results showed a significant reduction in both torsional vibrations and vertical movements, contributing to a more stable operation and reduced wear. The simulation proved to be in good agreement with the practical results, confirming that the polyurethane damper could effectively handle the combined forces. The improved stability also led to reduced maintenance intervals and an increased lifetime of the components that the damper protects.
Conclusion
This case study shows that a torsional damper made of polyurethane, capable of handling both torque and vertical forces, can be a very effective solution to reduce wear and improve reliability in complex applications. The combination of simulation, test casting and rigorous testing was crucial to optimise the performance of the damper and meet the specific requirements of the application in question.
