Abstract: A periodic linear time varying (LTV) model for on-off valve controlled pneumatic actuation systems, was described in an earlier paper by the authors. Based on this LTV model formulation, Floquet’s ...

Abstract: A new concept in the directional flow control of a high speed pneumatic actuation system is proposed. Two recent developments reported in the literature, namely (i) the application of pulse-width ...

Abstract: Nonlinear properties of a generic hydraulic mount with an inertia track are identified and characterized by using experimental and analytical approaches. A low-frequency lumped-parameter mathematical ...

Abstract: Sliding friction between meshing teeth is one of the primary excitations for noise and vibration in geared systems. Yet, there exist very limited studies on this topic. This paper proposes new ...

Abstract: An analytical solution to the dynamic transmission error of a helical gear pair is developed by using a single-degree-of-freedom model with piecewise stiffness functions that characterize the ...

Abstract: A finite element technique has been developed to find natural frequencies and modes of undamped three-dimensional acoustic cavities. This method utilizes the analogy between a special form of ...

Abstract: This paper describes an experimental method of determining sliding friction forces in a pneumatic actuator. Several empirical and semi-empirical friction models are evaluated using measured friction ...

Abstract: This paper studies the dynamic behavior of a pneumatic chamber connected to a reservoir through an orifice and to a linear mechanical system. In this paper, we focus our attention mainly on ...

Abstract: Analysis of brushless D.C. motor (BDCM) torque pulsations is an essential step in the diagnosis and control of vibration and noise generated by many electro-mechanical devices. The broad band ...
