常見(jiàn)例句雙語(yǔ)例句A new method for setting up the dynamic model of metal-rubber materials was proposed by using the equivalent viscous damping theory.提出了用等效粘性阻尼理論和試驗(yàn)相結(jié)合，建立金屬橡膠材料動(dòng)態(tài)力學(xué)模型的一種新方法。Comparing the fitted expression with the established theory expression of the angular velocity, the equivalent viscous damping coefficient is gained.比較角速度的理論表達(dá)式和擬合表達(dá)式，得出了運(yùn)動(dòng)副阻尼的等效粘性阻尼系數(shù)。The equivalent viscous damping ratio and the equivalent natural frequency are obtained by comparing the system with a purely linear, spring-mass-damper system of single freedom.通過(guò)和單自由度線性彈簧-質(zhì)量-阻尼系統(tǒng)進(jìn)行比較，得到該帶裂縫梁結(jié)構(gòu)的等效自然頻率和等效粘滯阻尼比。 返回 viscous damping
