A kind of impedance measurement is proposed with piezo - electric element which drives the beam and engender dynamic impedance data 摘要提出了利用压电陶瓷的阻抗测量法的概念,即用压电陶瓷作为驱动源产生动态阻抗信息。
5 . dynamic impedances of pile groups have been studied almost in a same assumption that rigid caps and soil under it do not touch each other in the present papers 5 .本论文在对群桩刚性承台动阻抗的求解过程中,首次考虑了承台底土与承台及群桩的动力相互作用。
The thesis account for the dynamic impedance of pile groups without the aboved - mentioned assumption . so , that the soil under caps affects the caps and piles is discussed 目前对群桩动阻抗研究的文献,始终局限在刚性承台底与土脱离的假设,而没有考虑实际存在的承台底与土接触的情况。
Vertical dynamic impedances of piles and rigid foundations of arbitrary shapes , vertical dynamic interactions between pile groups and raft foundations , optimization of pile groups are studied in the thesis . 1 论文围绕群桩竖向动阻抗、任意刚性基础的竖向动阻抗、群桩与承台板的竖向动力相互作用及群桩的动力优化布置进行了系统的研究。
In this paper , a simplified model for dam - foundation dynamic interaction analysis in time domain is proposed in terms of the studying of the characteristics of the dynamic impedance of canyon cut in elastic half - space 通过对拱坝地基的半无限空间动力体系的分析,提出了拱坝-地基动力相互作用问题的简化求解途径,并结合小湾拱坝进行了实际分析。
dynamic impedanceとは意味:動作{どうさ}インピーダンス dynamic impedance meaning:[Electronics] The impedance of a device (such as a transistor or diode) when it is operating with an applied alternating-current (ac) signal, as opposed to its static resistance with only direct...dynamic impedance перевод:динамическое полное сопротивление
