Abstract: The objective of the paper is presenting a simple and more      accurate technique      for precise identification of nonlinear elastic force functions      acting in      asymmetric vibration systems. The identification procedure based      on the Hilbert      transform is a nonparametric one; it does not require a priori      information      about the system structure or its parameters. The example of the      identification      of asymmetric classic vibration nonlinear models – the Helmholtz      oscillator –       is investigated.
