Bently Nevada Questions

Sabbatical – Career Builder Or Career Damper

A novel vibration damper concept for use in high-speed rotating machinery has been conceived and evaluated. The novel concept is coming as a complementary damping mean to any kind of the existing rotor system stability source on the machine.

Unlike other development in this field that includes just one damping principle, this approach is based on two principles mixed into the same unit: i) the principle of a dynamic vibration absorber and ii) the principle of a “stick” phenomenon that appears in dry-friction between two surfaces in a each other relative motion.

Therefore, in principal, the damper is a bearing-carrier that realize improving of the rotor dynamics: 1) by tuning the dynamic features of the damper (mass, stiffness) to the rotor features – resulting a restoring force and 2) by dissipating the rotor energy using a predetermined “stick” friction – that increases efficiency and enlarges the action area. An above depicted bearing-carrier vibration damper was specially designed to be proper for testing on the Bently Nevada Rotor-Kit. The experimental evidence proved the feasibility of the concept and quantified the damping effect showing large reduction in pick vibration at the critical speeds as well as in the magnitude of the resultant forces transmitted from the rotor to the stator.

Conclusions

A bearing-carrier vibration damper holds out the following benefits:

- provides a soft running to the rotor and implicitly to the machinery;
- sets rotor apart from the external mechanical transmitted perturbations;
- is independent of the running agent sources;
- is complementary to any kind of damping;
- is suitable to be used with any kind of rotor bearing system;
- provides certain self-alignment capability; supports high temperature; constructively is very simple.
