SBIR Phase I: Novel Passive Material to Achieve Vibration Isolation

这个小型企业创新研究第一阶段项目将探索被动减振材料的新概念。如果成功，得到的新材料在吸声、隔振和隔震方面的频率范围将比目前可用的材料高得多。以前的工作已经产生了一种新的吸声和振动材料，具有几个有价值的特性，包括在低至30赫兹的频率下显著衰减。这项工作导致了人们对如何制造更好的噪音、振动和减震材料的理解。这项研究将开发的新材料将是被动的、轻的、高度可靠的，并且可以低成本生产。这种材料的另一个好处是，衰减发生的机制是六个自由度。应用包括将精密设备与安装结构的振动隔离，高精度机床、光刻机、扫描探头显微镜和类似设备的振动隔离。它还将用作汽车和飞机等设备的新一代减振器。

This Small Business Innovation Research Phase I project will explore a new concept in passive vibration absorbing material. If successful, the resulting new material will have vastly superior performance over a broader range of frequencies for sound absorption, vibration isolation, and impact isolation than currently available materials. Previous work has yielded a new sound and vibration absorbing material with several valuable properties including significant attenuation at frequencies as low as 30 Hertz. That work has lead to an understanding of how to build better materials for noise, vibration, and shock attenuation. The new material to be developed in this research will be passive, light, highly reliable, and can be produced at low cost. Another benefit of the material is that the mechanism by which attenuation occurs is six degree of freedom. Applications include isolation of delicate equipment from vibrations of the structure to which they are mounted, vibration isolation for high precision machine tools, lithography machines, scanning probe microscopes, and similar equipment. It will also be usable as a new generation of vibration dampers on equipment such as automotive vehicles and aircraft.
