Numerical analysis of a dual-chamber hydro-pneumatic suspension using nonlinear vibration theory and fractional calculus

A dual-chamber hydro-pneumatic suspension, a modified version of the traditional hydro-pneumatic suspension, can provide enhanced isolation performance. In this article, we use two very different theories, nonlinear vibration theory and fractional calculus theory, to analyze the characteristics of a...
