Abstract
To obtain the accurate values of five parameters in the equation of damped oscillation of balance beam, the time interval measuring method is theoretically extended, which was developed for esitimating four parameters in the equation of undamped oscillation. A method of successive approximation for estimating the five parameters based on the five time intervals at every period is developed, with the aid of a personal computer. According to a numerical simulation, the estimated values except the attenuation constant are in good agreement with the given values within 10-4 at the 4th approximation.
The discussion is also described on better conditions for the time interval measurements.
