Abstract

The present invention provides a damper and a testing machine thereof. The damper comprises: a housing for a core rod to pass through; The outside of the rod; the second vibrator, the second vibrator is set in the housing, and the second vibrator is used to be sleeved on the outside of the first vibrator; the first vibration damping part, the first vibration damping part is set between the first vibrator and the second vibrator to reduce the vibration caused by the core rod. The damper of the invention solves the problem that the damper in the prior art cannot meet the vibration reduction requirements of an overspeed testing machine.

Description

Technical field[0001]The invention relates to the field of testing, in particular to a damper and a testing machine with the damper.Background technique[0002]In the test of measuring the rotation speed of the rotor, due to the high rotation speed of the test piece, coupled with its own experimental equipment or the processing of the test piece, it is easy to cause the vibration of the test piece, which leads to the strong vibration of the entire system. This strong vibration It will make the equipment unable to test and even damage the equipment. Existing equipment generally uses dampers and other devices to slow down and absorb the vibration of the equipment, but the dampers of the existing equipment are not very effective in absorbing vibration, and affect the rotation speed of the test piece. The power consumption can only adapt to the vibration caused by the rotation at a relatively low speed. When the rotation speed of the test piece is large, the existing dampers cannot meet t...
