additional mass meaning in Chinese
补充质量
附加质量
Examples
- This thesis intends to extend the frequency range of a shaker , minimize the impact of the additional mass and stiffness on the assessment results and make the frequency property of a shaker flat
本文旨在拓宽激振器的使用频率范围，减小激振器附加质量和附加刚度对测试结果的影响，并使激振器具有平坦的频率特性。 - Then the general plan of underwater vibrators is put forward . in chapter 3 , combining fluid - solid coupling theory and mechanical vibration theory , we get the coupling equation of moving parts and water . the dynamic characteristics of moving parts are studied with theory of finite element , and additional mass of moving parts is found in fluid - solid coupling field , which makes vibrator ' s natural frequency descend and amplitude - frequency curve downward shift
第三章运用流固耦合理论和机械振动学理论相结合的方法建立运动部件与水的耦合运动方程，利用有限元法对其的动态特性进行了研究，得到了在流固耦合场下运动部件存在的附加质量，该附加质量导致固有频率下降，单位推力下的加速度频响曲线整体下移。
