“…To improve AHP method, FAHP has been proposed. [31][32][33][34][35] In FAHP, 1-3 levels scale is used to construct the judgment matrix; so, experts can easily make the decision that which one has a higher priority between two indexes. Experts' fuzzy priority judgment matrixes can be directly transformed to fuzzy consistent matrixes, so there is no need for consistency check or adjustment.…”

In this article, a conjunctive multiple-criteria decision-making approach for cloud service supplier selection of manufacturing enterprise is proposed. According to the two perspectives of technology and technology management, the index framework of cloud service supplier selection is constructed from four dimensions: cloud service performance, supplier capability, supplier service level, and supplier service quality. Then, a conjunctive multiple-criteria decision-making approach is built. Neural network is used to realize the expert importance degree determination; fuzzy analytic hierarchy process considering the expert importance degree is used to determine the subjective weight; and CRITIC (CRiteria Importance Through Inter-criteria Correlation) is used to determine the objective weight. The multi-weight contribution equilibration model is built to integrate the subjective and objective weight. Finally, the improved TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) replacing Euclidean distance with connection distance is used to sequence the suppliers by their weighted index-value matrix. An automotive manufacturing enterprise application is given finally. The proposed approach can provide a scientific and efficient solution for cloud service supplier selection of manufacturing enterprise.

“…Guo et al [26,27] presented a multiaxis loading device (MLD) to simulate the loading condition of an operating feeding system of a machine tool in a real machining process. Hu et al [28] designed a reliability test rig based on a power dynamometer and piezoelectric loading device to conduct dynamic loading tests of the motorized spindle. Being restricted to the displacement of piezoelectric ceramics, it is hard to meet the rotation characteristic of the high-speed motorized spindle.…”

To realize the accurate performance test under high-speed operation and the long-term stable reliability test of the motorized spindle, a reliability test rig (RTR) which can simulate the cutting force in the actual machining process is presented. Firstly, a reasonable prototype integrating dynamic force loading devices and torque loading devices is designed and established based on the load analysis of the spindle, and a complete and explicit control strategy of the reliability loading test is designed. Secondly, the effects of misalignment of the diaphragm coupling caused by assembling are analyzed, and experiments are conducted to test the axis orbit of the motorized spindle. The experimental results illustrate that the axis orbit can identify the occurrence of misalignment, which ensures timely adjustment of misalignment and the accurate performance test under high-speed operation. Lastly, a damper is added in the mechanical structure of the electrohydraulic servo loading system (EHSLS), and the comparison of Bode maps before and after optimization is analyzed by the Nyquist criterion. After the optimization, the gain and phase margin of the Bode diagram are 12.9 dB and 57.2°, respectively, which are both within the stable range and validate the improvements on the ability of long-term reliability tests of the motorized spindle. The presented RTR is able to simulate the actual cutting force and provides an efficient loading approach to guarantee the accuracy and stability of motorized spindle tests.

“…However, dynamometers will generate abundant frictional heat and physical deterioration during high-speed rotation. When the rotational speed is over 20,000 rev/min, there are increased equipment vibration and noise (Hu et al, 2012). Hence, it is difficult for the dynamometer method to ensure the stable running of an HSMS under a loaded operation.…”

A high-speed dynamic loading test is a key step when testing the dynamic performance and running quality of a high-speed motorized spindle. A loading test is very difficult to perform at high speeds. Based on the rheological behavior of the magnetorheological fluid, a novel high-speed dynamic loading system for a high-speed motorized spindle was designed, fabricated, and tested. The working principles and structure of this loading system are described. The torque model of the loader was derived based on the Herschel–Bulkley model and electromagnetic simulation using the finite element method. In addition, the torque–current relationship under different speeds was analyzed by experiments, and we found non-linear relationships between the viscosity and shear stress of the magnetorheological fluid with the shear rate. The Herschel–Bulkley model was corrected by fitting for the experimental results. The loading torque, calculated by the modified model, complied with the experimental results. This lays the foundation for the design of a high-speed transmission device based on the magnetorheological shear principle. Experiments of torque stability, temperature stability, and reusability verified the feasibility and accuracy of the proposed loading system. It provides a novel method to test the dynamic loading performance of high-speed motorized spindles.
