He, Jihuan Preliminary report on the energy balance for nonlinear oscillations. (English) Zbl 1048.70011 Mech. Res. Commun. 29, No. 2-3, 107-111 (2002). Summary: We develop a reliable technique for calculating angular frequencies of nonlinear oscillators. The new algorithm offers a promising approach by constructing a Hamiltonian for nonlinear oscillators. Some illustrative examples are given.
