Counterfeiting of refrigerants has seen a dramatic rise over the past two decades. This rise can be partially attributed to global restrictions placed on production and use of refrigerants by the 1987 Montreal and the 1997 Kyoto Protocols (1, 2). These Protocols regulate the gradual phase-out and strict regulations on the use of refrigerants with high Ozone Depletion Potential (ODP) and high Global Warming Potential (GWP). These protocols require that older refrigerants shall be replaced with newer, more expensive, and environmentally friendly chemicals (3, 4) and necessitates redesigned or replaced equipment to operate efficiently with these new refrigerants.
Abstract Chatter vibrations are causing large monetary losses daily in industry. New materials have increased the challenges with harmful vibration levels. Since the vibrations, when observed as a final result, are chaotic and the vibration process nonlinear, it is a challenging task to deal with it. It is also a common “understanding” in the cutting industry that chatter is RPM (the rotational speed) dependent, since the behavior changes with RPM. Many attempts have been done over many years to mitigate and understand the vibrations. In our vast research on these topics, we have found that it is rewarding to classify the vibrations into categories, enabling a better understanding of its underlying physics and “source of vibrations,” and thus also the formulation of a possible remedy. An analysis approach has been developed where vibrations are analyzed and categorized and a GO/NOGO indicator is telling if the machine has the “right type of vibrations.”
Comparative Assessment of Frequency Dependent Joint Properties Using Direct and Inverse Identification Methods
Abstract Elastomeric joints are utilized in many automotive applications, and exhibit frequency and excitation amplitude dependent properties. Current methods commonly identify only the cross-point joint property using displacement excitation at stepped single frequencies. This process is often time consuming and is limited to measuring a single dynamic stiffness term of the joint stiffness matrix. This study focuses on developing tractable laboratory inverse experiments to identify frequency dependent stiffness matrices up to 1000 Hz. Direct measurements are performed on a commercial elastomer test system and an inverse experiment consisting of an elastic beam (with a square cross section) attached to a cylindrical elastomeric joint. Sources of error in the inverse methodology are thoroughly examined and explained through simulation which include ill-conditioning of matrices and the sensitivity to modeling error.
