Abstract Taking a quasiperiodic driven nonsmooth system with Farey tree as the research object, the existence of the strange nonchaotic attractor is confirmed and its statistical properties are further analyzed. Firstly, the fractal properties of strange nonchaotic attractor are analyzed by using phase diagram and power spectrum qualitative methods. The properties of strange nonchaotic attractor are described by means of maximum Lyapunov exponent, phase sensitive function, recursive analysis, spectral distribution function and finite-time Lyapunov exponent distribution. The results show that there are strange nonchaotic attractors in the system, and strange nonchaotic attractors exhibit a variety of statistical properties different from other types of attractors.
