摘要
在光电设备的结构设计中应用阻尼合金,可在振动环境下发挥阻尼合金的隔振作用而保护设备内部器件,并同时满足设备精度性能对于结构高刚性的要求。将复相型Zn-Al阻尼合金制成隔振构件,安装于某光电设备的模拟件,在振动和冲击条件下进行响应量值的测量和分析。对比普通铝合金,Zn-Al阻尼合金构件使设备振动响应加速度总均方根值平均减少10%,系统阻尼比增大40%;发挥阻尼合金振动衰减作用,关键是要使合金构件因共振而产生适度的应变。通过对不同结构形式的Zn-Al阻尼合金隔振性能的测试分析,为阻尼合金的工程应用提供技术参考。
In the structure design of the electro-optical equipment, the damping alloy is applied to protect thedevices in the equipment under vibration environment, meanwhile the structure high rigidity requirement for theequipment accuracy is met. Multiphase Zn-Al damping alloy is made into isolating vibration components to assem-ble into an electro-optical equipment model. The equipment response data is measured and analyzed in the environ-ment of vibration and shock. In comparison with components made by normal aluminum alloy, the response acceler-ation root-mean-square（RMS） average is reduced 10% by Zn-Al damping alloy components, the damping ratio ofthe system increases 40%. For playing the vibration attenuation effect of damping alloy, the moderate amount ofstrain must be generated in components due to the damping alloy component resonance. Through testing and analyz-ing on the attenuating vibration performance of damping alloy with different mechanical structures, some referenceinformation is provided for the application.
