根据变刚度原理，吸收橡胶隔振器高阻尼和金属弹簧隔振器高承载力的优点，采用新型材料，设计了一种由特形弹性元件以及弹性阻尼限幅装置组合而成的复合结构隔振器．该隔振器承受载荷能力大、压缩量小、阻尼大，并且散热快、寿命长、受环境因素影响小．理论分析及试验结果表明，该隔振器可以较好地隔离振动，并且隔振性能稳定． According to the principle of variable stiffness, absorbing the advantages of high damping of rubber vibration isolator and high bearing capacity of metal spring vibration isolator, a new type of material is used to design a composite structure consisting of special elastic element and elastic damping limiting device Shock absorber. The vibration isolator to withstand load capacity, compression is small, large damping, and heat dissipation, long life, subject to environmental factors. Theoretical analysis and experimental results show that the vibration isolator can isolate the vibration better and the vibration isolation performance is stable.
