A simple measurement system has been set up with PSD (Position Sensitive Detector) and the LabVIEW onPC (Personal Computer). To match this system, the apparatus of bifilar pendulum has been made, that is, a uniform metalbar suspended by two strings. Free vibration of the bifilar pendulum has three modes of vibration, three swinging modesand one twisting mode. One typical mode is used to test the measurement system, and the resulting performance data andits simulation are reported. This pendulum will be modified so as to have many swinging pendulums, which is addressedto make experimental apparatus, measurement system and numerical simulation. The results obtained are expected toprovide new education materials and to apply in Earthquake Engineering, Seismic Design and multi-body dynamics.
