Abstract

Abstract: To satisfy the need of reducing vibration of aero-engine, Metal Rubber （MR） isolator is designed and compared with rubber isolator experimentally. It is shown from the results that the performance of dissipating energy, load capacity, passing resonance and the range of vibration protection of MR isolator are much more excellent than those of rubber isolator. The isolating effects of MR isolator can be optimized by changing structural parameters and pre-compressing value of the elastic elements. The results of research offer evidences for MR isolator being applied to improve the vibration condition of aero-engine.
