Enhanced He's frequency-amplitude formulation for nonlinear oscillators Academic Article in Scopus uri icon

abstract

  • © 2020 The AuthorsIn this article, a trial residual Jacobi elliptic weighted function is introduced to obtain the frequency-amplitude expression of nonlinear oscillators using He's formulation. Simulation results show an improvement in the accuracy of the frequency values when compare to numerical integration simulations.
