摘　　要：利用动态热机械分析仪(DMA)、有限元分析软件Patran&Nastran和振动测试设备(DH5981),研究了M2052合金的阻尼性能及应用在支撑底座中的减振性能.振动测试结果与有限元分析结果比较吻合.结果表明:在频率响应分析中,M2052的应用能够有效降低振动,明显减小振动源产生的振动经支撑底座的传递;在瞬态响应分析中,通过振动衰减曲线对比看出,阻尼合金应用到工字型支座能更快的耗散振动能量,在一定范围内阻尼合金的应变越大,阻尼性能越好,所以S型支座能提供更大的减振性能;同时,通过力锤敲击实验验证了M2052合金在结构件中的应用能有效降低机械振动,且应变越大支座的减振效果越好.Dynamic thermal mechanical analyzer （DMA）, finite element analysis software Patran＆Nastran and vibration testing equipment （DH5981） were used to study the damping properties of M2052 alloy and the vibration damping perfor- mance applied in the support pedestals. The vibration test result was consistent with that of finite element analysis. The frequency response analysis showed that the application of M2052 can effectively reduce the vibration of the support pedestals, and the transmission of vibration produced by the vibration source was significantly reduced by the support pedestals. In transient response analysis, by comparing the vibration attenuation curve, it can support faster vibration ener- gy dissipation when damping alloy is applied to the I-shaped support pedestal. Within a certain range, the strain is larger, the performance of damping is better, thus S-shaped support pedestals can provide greater vibration reduction perfor- mance. At the same time, the force hammer percussion experiments has verified that the application of M2052 alloy in the structures can effectively reduce the mechanical vibration, and the strain is larger, the vibration damping effect of support pedestals is greater.
