In this kind of seismometer, the L-4C-3D short-period velocity seismograph are generally being used, since it has been designated as a specification criterion of velocity seismograph by Japan Meteorological Agency. In this study, with the L-4C vertical directional short period seismometer as objects to be analyzed, the seismic system structure using nonlinear springs and its vibrational properties are examined. In addition, the simple equipment of a seismic system having nonlinear springs is developed and the vibrational properties of the equipment are compared with that of the actual equipment experimentally.}, pages = {51--60}, title = {速度型地震計で利用する非線形ばねの試作および基本特性評価}, volume = {49}, year = {2020}, yomi = {ボンコバラ, ヤスヒロ and ハマハタ, タカユキ and テラゾノ, シンイチ and ハマハタ, タカユキ and テラゾノ, シンイチ and マエダ, タカヒロ} }
