Linearization of Intrinsically Nonlinear Oscillators
《Journal of Applied Mathematics and Physics》2024年第8期2829-2835,共7页Pirooz Mohazzabi Qinghua Luo Ilirian Dhimitruka 
We show that an intrinsically nonlinear oscillator can always be transformed into a linear or harmonic oscillator by addition of a constant force, which shifts the equilibrium position of the oscillator.
