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 文中詳細介紹了離散單元法的基本原理、破壞準則、基本方程以及彈簧剛度系數(shù)、阻尼系數(shù)、時間步等計算參數(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 同時瀝青對彈簧剛度變化有明顯的影響,從實驗結果可以看出,彈簧剛度越大,則瀝青對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 主要內容如下: 1 .分析了微機械陀螺的運動特性、靜電驅動特性和在大氣下的阻尼特性,分析結果表明,可以運用切向靜電力驅動質量塊振動,法向靜電力對器件特性的影響可以忽略;在計算微結構電容時,電容的邊緣效應和寄生電容不可忽略;在器件所受阻尼主要為庫埃特流阻尼的情況下,阻尼力系數(shù)較小。
