Abstract: Free piston Stirling engines (FPSEs) are examples of closed cycle regenerative engines, which can be used to convert thermal energy into mechanical energy. These engines are multidegreeoffreedom dynamical systems, which ...

Abstract: A probabilistic approach is needed to address systems with uncertainties arising in natural processes and engineering applications. For computational convenience, however, the stochastic effects are often ignored. Thus, ...

Abstract: Legged locomotion has advantages when one is navigating a flowable ground or a terrain with obstacles that are common in nature. With traditional terra-mechanics, one can capture large wheel–terrain interactions. However, ...

Abstract: Professor Linda Schmidt, a pioneering leader in engineering design research and education, passed away on Mar. 12, 2021.She was born in Blue Island, Illinois, on Nov. 27, 1958, and received her B.S. degree (1989) and M.S. ...

Abstract: In this paper, the authors present a discrete system model to study the coupled axial–torsional dynamics of a drill string. The model is developed taking into account statedependent time delay and nonlinearities due to ...

Abstract: In the current study, the authors examine the torsional vibrations of a rotor enclosed within a stator subjected to dry friction. Through the experiments, it is demonstrated that forward whirling of the rotor occurs while ...
