Abstract:
A vibration system with discontinuities has triggered off rocketing interest in various fields
including mechanical engineering, physics, and mathematics because it has many striking and
amazing properties which cannot be unexplained by traditional vibration theory. This paper
studies the problem using the energy conservation frame in a fractal time. A variational formulation is developed, and its periodic property is elucidated by the frequency–amplitude formulation. For discontinuity, this paper aims to propose a new frequency formulation by means of the golden average. Comparison between the approximate and exact frequency values is presented to validate our method.
