Abstract
This paper describes the experimental results on the dynamic behavior of the Belleville springs stacked in series with washers and some process for deducing its dynamic character from the static load-deflection curve. Comparing the experimental results with those of the calculation, it is concluded that:
(1) For demonstrating the hysteresis phenomena on a static load-deflection curves of the Belleville springs stacked in series with washers, it is necessary to take the frictional force between the contact surfaces into consideration. Thus, the experimental results agree fairly well with the calculated ones.
(2) It is found that both the dynamic spring constants and the equivalent damping coefficients change in accordance with the amplitudes as well as the exciting frequencies, and those take the minimum values in the vicinity of the resonant frequency. And it can be said that vibration characteristics are the non-linear ones with soft-spring tendency.
(3) According to the process described in this paper, it is possible to deduce the dynamic character of the Belleville springs stacked in series quantitatively from the calculation.
