Although theoretical analysis and experiments on this problem have been attempted by others, the stability analysis for the jumping granular solid has not been carried out. In this paper an exact solution for the periodic motion of the jumping granular solid is derived, and its stable regions are determined. The following conclusions can be drawn from this paper. (1) When the coefficient of restitution R≐̸0,the stability boundaries K is given by [numerical formula] (2) When R=0 and the relative acceleration of the granular solid just after an impact y_0>0,K is given by [numerical formula] (3) When R=0 and y_0<0,K is given in the table, in which K=bω^2/(gcosα), b : amplitude of the track surface. ω : angular frequency. g : acceleration of gravity. α : inclination of the track surface. n : 1,2,3,…….
