GR2 Series
Technical Principles and Structural Innovation of GR Series
Isolators
The GR series wire rope isolator (commonly known as
"butterfly-shaped") developed by Xi'an Hoan Microwave Co., Ltd. is
a high-performance vibration damping device based on the principle
of nonlinear damping. Its core is composed of multiple strands of
stainless steel wire ropes braided according to a specific
topological structure, forming a unique double-axis symmetric
butterfly wing shape. This design not only endows the isolator with
360° omnidirectional impact resistance, but also converts
mechanical vibration into heat energy for dissipation through the
friction energy dissipation mechanism between the wire rope
strands.
Compared with traditional rubber isolators, the innovation of the
GR series lies in the absence of aging hazards - the metal material
completely avoids the defects of rubber that is prone to oxidation
and deterioration, and its service life can reach more than 20
years. At the same time, it has environmental universality, and its
performance is stable in extreme temperature ranges from -55℃ to
+200℃ and harsh working conditions such as salt spray and oil
pollution. Measured data show that its suppression effect on the
vibration transmissibility in the 15-500Hz frequency band exceeds
60%, and it is particularly good at protecting precision
instruments from low-frequency impact interference.
