点阻抗 meaning in Chinese

point impedance

Vibration and shock - mechanical driving point impedance of the human body
人体的机械驱动点阻抗
Subsequently , the method is verified by a numerical example of a simply supported beam , and some graphs depicting the driving point impedance characters of the simple supported cracked beam are drawn
以一裂纹简支梁为例进行了数值分析，得到了裂纹简支梁的驱动点阻抗特性曲线。
To characterize the local discontinuity due to the crack , a rotational spring model is proposed to model the crack , on the basis , a method for crack identification is presented in this paper , which makes use of the driving - point mechanical impedance characters of the cracked beam stimulated by harmonic force
为了描述由裂纹引起的梁中波传播的不连续特性，引入弯曲弹簧模型来模拟裂纹，并在此基础上提出了利用梁结构驱动点阻抗特性的裂纹损伤识别方法。
