In this paper, we investigate systematically the vibration of a typical 2DOF nonlinear system with repeated linearized natural frequencies. By application of Descartes’ rule of signs, we demonstrate that there are 14 types of roots describing different modal motions for varying nonlinear parameters.

Bifurcation Trees of Period-1 Motions to Chaos in a Two-Degree-of-Freedom, Nonlinear Oscillator
International Journal of Bifurcation and Chaos, 2015In this paper, analytical solutions for period-[Formula: see text] motions in a two-degree-of-freedom (2-DOF) nonlinear oscillator are developed through the finite Fourier series. From the finite Fourier series transformation, the dynamical system of coefficients of the finite Fourier series is developed. From such a dynamical system, the solutions of

Saddle-node or period-doubling bifurcations of the near-grazing impact periodic motions have been extensively studied in the impact oscillators, but the near-grazing Neimark-Sacker bifurcations have not been discussed yet.

Similar Motion of Two-Degree-of-Freedom Nonlinear Vibrating Systems with Nonsymmetric Springs
IBM Journal of Research and Development, 1967If similar motion occurs, it is demonstrated by a straight line (linear trajectory) in the configuration space whose orthogonal coordinates are the displacements of the masses in the vibrating system. Since the systems considered are conservative, all solutions of the equations of motion must satisfy the Principle of Least Action and its Euler-Lagrange

Development of control system for two degree of freedom hydraulic motion base
2010 2nd International Conference on Mechanical and Electronics Engineering, 2010this paper introduces a mechanism of two degree of freedom hydraulic motion base used for flight simulator. The new system reduces the cost and complicity by using a ball as a base. The performance of the system is then evaluated by using Simscape Matlab Simulink. PI controller is added to improve the overall system response.

Design and analysis of two degrees of freedom flexure hinges with remote center of motion
Review of Scientific InstrumentsThis paper presents the design, analysis, fabrication, and testing of a series of two degrees of freedom (2-DOF) Remote Center of Motion (RCM) flexure hinges. These hinges are constructed using planner generalized cross-spring pivots according to the building block approach.

Robots play an increasingly important role in the development of minimally invasive surgery (MIS). In MIS assistant robot systems, the remote center of motion (RCM) mechanism is a key component, and is the primary choice as end-effector for such systems.
