โœฆ Synopsis

Non-linear vibration in a driveline which incorporates a Hooke's joint is presented in this paper. In particular, torsional vibration due to #uctuating angular velocity ratio across the joint is examined. Linearized equations are used for the prediction of critical speed ranges where parametric instabilities characterized by exponential build up of torsional response amplitudes occur. Predicted instabilities indicate the range of driveshaft speeds to be avoided during the design of a driveline which employs a Hooke's joint. Numerical simulations and bifurcation analysis performed on the full non-linear equations further demonstrate the existence of parametric, quasi-periodic and chaotic motion. Onset of chaotic motion was shown to be characterized by a quasi-periodic route.

Dynamic instabilities in a torsional system which incorporates a Hooke's joint are investigated by means of Lyapunov exponents. Linearized analytical models for the torsional system are established for the purpose of stability analysis. The resulting two-degree-of-freedom system is parametrically ex

In this paper a non-linear discrete-continuous model of a multi-mass system torsionally deformed with a local non-linearity is investigated. It is assumed that the characteristic of the local non-linearity is of a soft type. Four non-linear functions describing this characteristic are proposed. In t
