“…Based on the results, they stabilized the temperature in the structure and eliminated thermal errors. In-process spindle health monitoring was conducted by Yan et al [323], who proposed a stochastic subspace-identificationbased approach for that purpose, and by Lee et al [324], who monitored the displacement variation using a laser rather than displacement sensors. Further industrial developments will increase the need for instrumented fluid lubricated bearings that monitor the key performance indices and correspondingly optimize the structure.…”

Fluid lubricated bearings have been widely adopted for supporting components of high-end equipments in the field of metrology, semi-conductor, aviation, strategic defense, ultra-precision manufacturing, medical treatment and power generations. These fields all involve extreme working conditions such as ultra-high moving precision, ultra-high rotation speed, ultra-heavy bearing load, ultra-high environmental temperature, high radiation and high vacuum, which present challenges for the design and optimization of reliable fluid lubricated bearings. Breakthrough of any related bottlenecks will promote the development course of high-end equipments. To further promote the advancement of high-end equipments, this paper reviews the design and optimization of fluid lubricated bearings operated with typical extreme working performances. Targeting on the realization of extreme working perfor mances, the current challenges, the current solutions, the underlying deficiencies and the promising developing directions regarding to the design and optimization of fluid lubricat ed bearings are systematically pointed out. This paper can provide guidance for choosing suitable fluid lubricated bearings and optimizing their structures based on required extremeworking performances.

Over the past century, research has focused on continuously improving the performance of manufacturing processes and systems—often measured in terms of cost, quality, productivity, and material and energy efficiency. With the advent of smart manufacturing technologies—better production equipment, sensing technologies, computational methods, and data analytics applied from the process to enterprise levels—the potential for sustainability performance improvement is tremendous. Sustainable manufacturing seeks the best balance of a variety of performance measures to satisfy and optimize the goals of all stakeholders. Accurate measures of performance are the foundation on which sustainability objectives can be pursued. Historically, operational and information technologies have undergone disparate development, with little convergence across the domains. To focus future research efforts in advanced manufacturing, the authors organized a one-day workshop, sponsored by the U.S. National Science Foundation, at the joint manufacturing research conferences of the American Society of Mechanical Engineers and Society of Manufacturing Engineers. Research needs were identified to help harmonize disparate manufacturing metrics, models, and methods from across conventional manufacturing, nanomanufacturing, and additive/hybrid manufacturing processes and systems. Experts from academia and government labs presented invited lightning talks to discuss their perspectives on current advanced manufacturing research challenges. Workshop participants also provided their perspectives in facilitated brainstorming breakouts and a reflection activity. The aim was to define advanced manufacturing research and educational needs for improving manufacturing process performance through improved sustainability metrics, modeling approaches, and decision support methods. In addition to these workshop outcomes, a review of the recent literature is presented, which identifies research opportunities across several advanced manufacturing domains. Recommendations for future research describe the short-, mid-, and long-term needs of the advanced manufacturing community for enabling smart and sustainable manufacturing.

A round link chain subject to axial dynamic loads composes a nonlinear viscoelastic system. Unlike the classical pounding problems, the round link chain will not only suffer linear elastic deformation, but also nonlinear plastic or impacting deformation. Based on theoretical formulation and experiments, a new approach is presented in this paper to model and identify the nonlinear dynamic parameters, namely the stiffness and damping for the round link chain. With linear deformation, nonlinear deformation and energy dissipation considered, a modified nonlinear viscoelastic model is developed to describe the vibrational behavior of the chain with numbers of round links. The linear elastic model and impacting model are combined to derive the equivalent nonlinear stiffness, while experiments and the least square fitting method are employed to identify the nonlinear damping according to the modified nonlinear viscoelastic model. The influences of the key parameters such as the length of the chain, elastic module and loading frequency on the dynamic stiffness and damping are investigated. Another test is performed to validate the identification model and good agreements are observed.
