Abstract In this paper, the response properties of galloping energy harvesters under bounded random parameter excitation
are studied theoretically. The first-order approximate solution of the galloping energy harvester is derived by
applying the multi-scales method. The expression for the largest Lyapunov exponent that determines the trivial
solution is derived, and the corresponding simulation diagrams, including the largest Lyapunov exponent diagrams
and time domain diagrams, verify our results. Then the steady-state response moments of the nontrivial solution
are studied using the moment method, and the analytical expressions for the first-order and second-order moments
of the voltage amplitude… More >
