concentrated mass

基本解釋

In an equivalent dynamic simplified model of motor vehicle, the difference in vibration amplitude between first and second concentrated mass is quite great.
在汽車當(dāng)量動(dòng)力簡(jiǎn)化模型中，第一集中質(zhì)量與第二集中質(zhì)量之間振幅差值較大。
Some configurations include concentrated mass dampers attached to a brake rotor or pad. Some embodiments use multiple mass dampers that can be attached to the brake rotor or pad.
以及多個(gè)安裝至制動(dòng)盤的集中質(zhì)量阻尼器，其中集中質(zhì)量阻尼器設(shè)置成對(duì)制動(dòng)盤施加局部的力，在制動(dòng)總成中產(chǎn)生嘯叫降低的振動(dòng)。

Finally, the effect of the impedance, standing for a storage circuit, and the concentrated mass at the free end of the bimorph on the harvester performance is discussed in detail.
最后還詳細(xì)討論了儲(chǔ)能電路的阻抗，自由端懸掛的集中質(zhì)量對(duì)俘能器性能的影響規(guī)律。

But he also realized that when they did hit something what they hit what unbelievably massive but also that that mass was concentrated So eventually, this is what we have come to call the nucleus of an atom.
碰到的一定是十分重的東西,而且那些質(zhì)量,要聚集在非常非常小的空間內(nèi),這個(gè)就是我們稱作,原子核的東西。

And, on the basis of the study findings, the nature vibration frequency solution formula of the inflated beam with concentrated mass has been deduced. The analytical solution of the beam baseband modal frequency has been obtained.
從理論角度分析管狀或者由充氣管組成的充氣薄膜結(jié)構(gòu)的受力特性,以充氣支撐管為研究模型,從理論上研究了充氣支撐管軸向抗壓剛度和結(jié)構(gòu)整體抗彎剛度與管充氣氣壓之間的關(guān)系,并在此研究結(jié)果的基礎(chǔ)上,推導(dǎo)端頭帶集中質(zhì)量的懸臂充氣支撐管自振頻率的求解公式,并結(jié)合本文研究模型求出其基頻的解析解。
