概要

論文の詳細を見る
It is planned to make a simple measurement system with PSD (Position Sensitive Detector) and the LabVIEWon PC (Personal Computer). Prior to setting up the system, a pre-study is made here of linear and nonlinear vibrations ofbifilar pendulum, that is, a uniform bar suspended by two strings. A free vibration problem of the bifilar pendulum hasfour modes of vibration, two swinging modes, one twisting mode and TASUKIGAKE mode, and is extended to allow foran external excitation. The results obtained are expected to provide new education materials and to apply in EarthquakeEngineering and Seismic Design.
