“…Duffing oscillator is one of the most common and typical models in nonlinear dynamical systems. Among these nonlinear systems the well-known Duffing oscillator is quite suitable to model the large deformation structure in many physics and engineering fields [7][8][9][10]. Moreover, time delay is an unavoidable and very common problem when those systems were controlled.…”

The heteroclinic bifurcation and chaos of a Duffing oscillator with forcing excitation under both delayed displacement feedback and delayed velocity feedback are studied by Melnikov method. The Melnikov function is analytically established to detect the necessary conditions for generating chaos. Through the analysis of the analytical necessary conditions, we find that the influences of the delayed displacement feedback and delayed velocity feedback are separable. Then the influences of the displacement and velocity feedback parameters on heteroclinic bifurcation and threshold value of chaotic motion are investigated individually. In order to verify the correctness of the analytical conditions, the Duffing oscillator is also investigated by numerical iterative method. The bifurcation curves and the largest Lyapunov exponents are provided and compared. From the analysis of the numerical simulation results, it could be found that two types of period-doubling bifurcations occur in the Duffing oscillator, so that there are two paths leading to the chaos in this oscillator. The typical dynamical responses, including time histories, phase portraits, and Poincare maps, are all carried out to verify the conclusions. The results reveal some new phenomena, which is useful to design or control this kind of system.

The article contains a research of the influence of design parameters (material, the jamming angle) on operation reliability of eccentric friction-type freewheel mechanisms using calculated and experimental techniques. As the investigated factor, the lower limit of the confidence interval for the time between failures is adopted It is shown that the necessary reliability of the eccentric freewheel mechanisms is ensured when jamming angles are 8–10° and when their elements are made of material 100Cr6. The reliability of such mechanisms is 1.7 times higher than of roller free-wheel mechanisms. The results of the research can be used when predicting the reliability of the mechanisms in the drives of machines.

“…Motion and power are transferred from the drive pulley to the driven pulley via the friction between the belt and pulleys. [1][2][3][4][5][6] The reliability of the belt drive system plays an important role in the risk assessment and optimal design of mechanical products. Therefore, it is necessary to develop accurate reliability models of belt drive systems.…”

Conventional reliability assessment and reliability-based optimal design of belt drive are based on the stress-strength interference model. However, the stress-strength interference model is essentially a static model, and the sensitivity analysis of belt drive reliability with respect to design parameters needs further investigations. In this article, timedependent factors that contribute the dynamic characteristics of reliability are pointed out. Moreover, dynamic reliability models and failure rate models of belt drive systems under the failure mode of slipping are developed. Furthermore, dynamic sensitivity models of belt drive reliability based on the proposed dynamic reliability models are proposed. In addition, numerical examples are given to illustrate the proposed models and analyze the influences of design parameters on dynamic characteristics of reliability, failure rate, and sensitivity functions. The results show that the statistical properties of design parameters have different influences on reliability and failure rate of belt drive in cases of different values of design parameters and different operational durations.
