1) two to one frequency divider
频率减半器
3) frequency deceleration
频率减慢
4) shock absorbing frequency
减震频率
1.
The results indicate that this shock absorption system can enlarge the bandwidth of shock absorbing frequency and the arrangement of support is flexible,and the damping effect is relatively remarkable.
论述了影响复合加层减震设计的主要因素和复合减震层的特点,利用有限元软件对一复合加层减震建筑结构进行了时程分析,结果表明:复合加层减震体系支座布置灵活,并能增大减震频率的带宽,减震效果也比较显著。
5) attenuation frequency
衰减频率
1.
The results show that when the content of SiC is in the range from 1%(mass fraction,the same below) to 10%,the attenuation frequency of lossy resonance(f0) shifts to a low frequency as the effective attenuation bandwidth grows,and this effect is stronger when the content of SiC is less than 2%.
结果表明:当SiC质量分数(下同)从1%到10%逐渐增加时,复相材料的损耗谐振衰减频率(f0)随之降低,衰减量也逐渐减小,有效衰减带宽增大;这种现象在SiC含量小于2%时更显著。
