Evaluation of thermal imaging system and thermal radiation detector for real-time condition monitoring of high power frequency converters
Springer Science and Business Media LLC - Tập 2 - Trang 88-94 - 2014
Anders Eriksen, Dominik Osinski, Dag Roar Hjelme
We have carried out at laboratory test to study the feasibility of using thermal radiation detectors for online thermal monitoring of electrical systems in wind turbines. A 25 kW frequency converter is instrumented with a thermal camera, operating in the 8–14 μm wavelength range, and a single-pixel thermopile sensor, operating in the 4–8 μm wavelength range, to monitor the temperature development ...... hiện toàn bộ
Experimental and computational analysis of the coolant distribution considering the viscosity of the cutting fluid during machining with helical deep hole drills
Springer Science and Business Media LLC - Tập 10 - Trang 235-249 - 2022
Ekrem Oezkaya, Sebastian Michel, Dirk Biermann
An experimental analysis regarding the distribution of the cutting fluid is very difficult due to the inaccessibility of the contact zone within the bore hole. Therefore, suitable simulation models are necessary to evaluate new tool designs and optimize drilling processes. In this paper the coolant distribution during helical deep hole drilling is analyzed with high-speed microscopy. Micro particl...... hiện toàn bộ

Digital twin-driven green material optimal selection and evolution in product iterative design
Springer Science and Business Media LLC - Tập 11 - Trang 647-662 - 2023
Feng Xiang, Ya-Dong Zhou, Zhi Zhang, Xiao-Fu Zou, Fei Tao, Ying Zuo
In recent years, green concepts have been integrated into the product iterative design in the manufacturing field to address global competition and sustainability issues. However, previous efforts for green material optimal selection disregarded the interaction and fusion among physical entities, virtual models, and users, resulting in distortions and inaccuracies among user, physical entity, and ...... hiện toàn bộ
Local synthesis of carbon nanotubes for direct integration in Si microsystems – design considerations
Springer Science and Business Media LLC - Tập 1 - Trang 218-225 - 2013
Knut E. Aasmundtveit, Bao Quoc Ta, Quoc-Huy Nguyen, Tormod B. Haugen, Nils Hoivik, Einar Halvorsen
The integration of nanomaterials such as carbon nanotubes (CNTs) into microsystems is highly desirable, in order to make use of the unique nanomaterial properties in real devices. However, the CNT-to-microsystem integration is challenging to implement in a manufacturable, cost-effective industrial process. This paper presents our work towards a process for making complete, integrated CMOS / MEMS s...... hiện toàn bộ
Surface integrity of ball burnished bioresorbable magnesium alloy
Springer Science and Business Media LLC - Tập 11 - Trang 342-362 - 2022
G. V. Jagadeesh, Srinivasu Gangi Setti
Magnesium alloys are potential biodegradable and biocompatible implant materials because of their excellent biological properties. Recently, interest in these alloys as a promising alternative for temporary orthopedic implants has grown owing to their desirable biological, mechanical, and physical properties. However, the application of magnesium alloys is hindered by their rapid degradation and l...... hiện toàn bộ
Optimum calibration of a parallel kinematic manipulator using digital indicators
Springer Science and Business Media LLC - Tập 2 - Trang 222-230 - 2014
V. B. Saputra, S. K. Ong, A. Y. C. Nee
This paper presents a calibration method for parallel manipulators using a measurement system specially installed on an external fixed frame. The external fixed frame is important as an error reference for calibration in certain operations, such as in the configuration of a parallel manipulator functioning as a machine tool where the workpiece is fixed to a worktable. The pose of the end-effector ...... hiện toàn bộ

Improved time-optimal B-spline feedrate scheduling for NURBS tool paths in CNC machining
Springer Science and Business Media LLC - Tập 11 - Trang 111-129 - 2022
Yang Li, Fu-Sheng Liang, Lei Lu, Cheng Fan
Feedrate scheduling in computer numerical control (CNC) machining is of great importance to fully develop the capabilities of machine tools while maintaining the motion stability of each actuator. Smooth and time-optimal feedrate scheduling plays a critical role in improving the machining efficiency and precision of complex surfaces considering the irregular curvature characteristics of tool paths...... hiện toàn bộ
