Abstract

The invention provides a damper and a testing machine with same. The damper comprises a shell, a first vibrator, a second vibrator and a first vibration absorbing part, wherein the shell is used for acore rod to penetrate through; the first vibrator is arranged in the shell; the first vibrator sleeves the external side of the core rod; the second vibrator is arranged in the shell; the second vibrator sleeves the external side of the first vibrator; and the first vibration absorbing part is arranged between the first vibrator and the second vibrator to reduce vibration caused by the core rod.According to the damper, a problem that the damper in the prior art cannot satisfy vibration absorption of an overspeed testing machine is solved.

Description

technical field [0001] The invention relates to the field of testing, in particular to a damper and a testing machine with the same. Background technique [0002] In the test of measuring the rotation speed of the rotor, due to the high rotation speed of the specimen, coupled with the reasons such as the experimental equipment or the processing of the specimen, it is easy to cause the vibration of the specimen, which leads to the strong vibration of the whole system. It will make the equipment unable to test, or even damage the equipment. In the existing equipment, dampers and other devices are generally used to slow down and absorb the vibration of the equipment, but the vibration absorption effect of the damper in the existing equipment is not good, and it affects 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 relatively high, the exis...
