ZW—3/7无油压缩机基础支承的隔振器设计

Design of Base Support Isolator for ZW—3/7 Type of Oil-free Compressor

针对ZW—3/7无油压缩机在工作过程中基础振动剧烈,同时伴有较大环境噪声问题,在振动原因分析的基础上,利用主动隔振理论建立压缩机隔振系统动力学模型,进行隔振系统绝对传递率计算和阻尼系数确定。利用组合刚度设计思想,将弹簧和弹性多孔金属橡胶材料组合作为弹性元件进行隔振器参数设计,并借助Solidworks有限元软件仿真计算,结果符合强度、稳定性设计要求,且满足了ZW—3/7无油压缩机基础支承的隔振需求。

Aiming at the problem of great vibration and concomitant noise while the ZW-3/7 type of oil-free compressor is running, the dynamic model of compressor is built, based on the active vibration isolation theory and vibration causation analysis. The absolute transmissibility is calculated and damping coefficient is obtained. Helical spring and metal rubber which is one kind of poroelasticity material are assembled to act as the isolator＇s core element. Isolator＇s parameters are designed and simulation calculations are done using the finite element software Solidworks. It shows that the isolator design meets the requirements of intensity, stability and vibration isolation of the compressor.
