可変ばねおよび非線型復原力特性を併有する振動系の自由振動について

抄録

In this paper, we investigate the character of the free vibration of a system whose equation of motion is given by the formula : [numerical formula], and compare the results of the calculations with those of the experiments. In our calculations, we assume a sinusoidal solution with half frequency of variable as a periodic one. Adopting the new method of successive approximation, we obtain theoretical expressions for this problem with sufficient accuracy. This enables us to examine the stability of vibration. It is shown that coincidence between our calculations and experiments very satisfactory.
