Theoretical analysis and experiments were carried out in connection with the speed of granular solid when repeating bath sliding and jumping movements on the oscillating trough in straight line motion. In this case, solid on the trough makes regular repetition of the process such as sliding movement in the plus and minus directions, jumping movement and relative rest, for which the relative displacement Δx_i is made clear. Travelling speed V is, consequently, concluded as [numerical formula], and by using the formula, numerical calculation is made possible. In order to find the coefficient of friction between solid and trough, which is necessitated for this analysis, we adopted a method different from conventional one. Our method is this : measuring by oscillograph the acceleration transmitted to solid from the trough. As for the measures of friction and travelling speed, we could investigate over a wider range by using the oscillating apparatus designed by us, which has various directions of throw. And as a result of the investigation, it has been found that the experimental value shows approximate accordance with the theoretical analysis.
