This paper introduces a discrete wheel-switching chaotic system (DWSCS). Changing the controlling sequence of the wheel switch allows DWSCS to generate a large number of new chaotic sequences from a set of existing chaotic maps (seed maps). Simulations and analysis demonstrate the DWSCS's characteristics and chaotic behaviors. An FPGA design of DWSCS shows its effectiveness in hardware implementation...
A nonlinear dynamic model of planetary gear train with backlashes, time-varying stiffness and transmission errors, was developed to simulate the dynamics of the system. The motion equations of the system were deduced. The specific effect of the transmission errors on the dynamic behavior of the planetary gear system was investigated using digital simulation technique. The bifurcation diagrams of displacement...
A lumped-parameter model of a single-stage planetary gear train was established. The influence of the rotary inertia of the sun gear on the dynamical behavior of planetary gear train was investigated. The steady responses were obtained by using numerical method. The characteristic of the system was described by time history, phase plane plot, Poincare section and FFT spectrum. The result shown clearly...
Backlash may cause nonlinearity and dynamic loads in planetary gear train. A nonlinear dynamic model of a planetary gear train with time varying mesh stiffness and dynamic transmission errors was employed to study the effect of backlash on the load sharing amongst the planets. The dynamic response of the system was investigated by using digital simulation technique. The bifurcation diagrams of relative...
