Diversity between new type damping spring and common spring is its damper form variation and coefficient of damping increment 新型阻尼彈簧與普通彈簧的區(qū)別是阻尼表現(xiàn)形式的變化和阻尼系數(shù)值顯著增加。
Some basic concepts , failure criterion , formula and determination of analytical parameters such as spring modulus , coefficient of damping and time step of the extended model are presented 文中詳細(xì)介紹了離散單元法的基本原理、破壞準(zhǔn)則、基本方程以及彈簧剛度系數(shù)、阻尼系數(shù)、時(shí)間步等計(jì)算參數(shù)的確定方法。
At the same time , experiment shows that pitch has important effect on spring ' s rigidity . the greater the spring rigidity , smaller is the pitch ' s effect on coefficient of damping and spring ' s rigidity 同時(shí)瀝青對(duì)彈簧剛度變化有明顯的影響,從實(shí)驗(yàn)結(jié)果可以看出,彈簧剛度越大,則瀝青對(duì)其阻尼和剛度的變化影響越小。
By means of the theoretical analysis of the micromachined vibratory rate gyroscope , we get following conclusions : the microgyroscope can be driven by tangent electrostatic force produced by fence structure electrodes , and the normal electrostatic force can be neglected for the influence of the device property ; the parasitical capacitance and fringing effect can ’ t be neglected for the calculating of the detection capacitance ; the coefficient of damping force is comparatively little when the air damping in the driving mode and the sensing mode of the device is the couette flow damping 主要內(nèi)容如下: 1 .分析了微機(jī)械陀螺的運(yùn)動(dòng)特性、靜電驅(qū)動(dòng)特性和在大氣下的阻尼特性,分析結(jié)果表明,可以運(yùn)用切向靜電力驅(qū)動(dòng)質(zhì)量塊振動(dòng),法向靜電力對(duì)器件特性的影響可以忽略;在計(jì)算微結(jié)構(gòu)電容時(shí),電容的邊緣效應(yīng)和寄生電容不可忽略;在器件所受阻尼主要為庫(kù)埃特流阻尼的情況下,阻尼力系數(shù)較小。
