Dynamic behavior of globoidal cam systems with torque compensation mechanisms
چکیده انگلیسی

The correlation between the dynamic response of a globoidal cam (GC) system and the motor driving speed is investigated numerically and experimentally. Electrical–mechanical models of the GC system are presented for two different torque compensation mechanisms, namely a torque compensation cam (TCC) and a torque compensation flywheel (TCF). The two-step mesh stiffness model of the GC system, i.e. the stiffness for the active and dwell periods, is used to characterize the mesh stiffness fluctuation in the engagement. The dynamic intermittent-motion equations of the GC system are derived using Lagrange's equation and are simulated using the sixth-order Runge–Kutta iteration method. The variation of the driving speed caused by the intermittent motion is simulated and analyzed. The effectiveness of the torque compensation schemes in suppressing driving velocity fluctuations of the high speed GC system is also explored. The numerical results for the simulated dynamic response histograms of the high speed operating GC system are in good agreement with the experimentally measured data.
