摘　　要：为了提高锌基合金的阻尼性能,研究了添加纳米TiC颗粒对ZA合金阻尼性能的影响。结果表明,添加纳米TiC颗粒可以将锌基复合材料的阻尼比提高25%～35%,从而降低受迫振动的振幅,即可达到减振降噪的作用。这证明纳米碳化钛颗粒增强锌基复合材料在高速、高效、高自动化并需减振降噪的机械设备中有良好的应用前景。In order to improve the damping properties of zinc-based alloy,the damping performance of zinc-based alloy reinforced by nano-TiC particles were studied by experimental methods.The results show that the damping ratio of zinc-based composite can be increased by 25% to 35% by adding nano-TiC particles.Thus reducing the amplitude of forced vibration,the effect of vibration and noise reduction can be achieved.It proves that zinc-based composite reinforced by nano-TiC particles has a good prospect in mechanical equipment of high-speed,high efficiency,high automation,which need noise and vibration reduction.
